What Is a Hellboy Betta?

The Hellboy Betta is part of the Betta Splendens family. It's a high-quality coloration fish with the ever-popular plakat body and fin form that has become increasingly popular. This fish has a variety of color and may have 5 or more hues, although red is consistently prominent in the mix.

Every individual fish has a different pattern, making each fish unique. They are also known as Hellboy Plakat Halfmoon Betta due to its beautiful wavy halfmoon fins. The Hellboy halfmoon betta fish is named for its cherry red and blue hues, which are the primary colors that define this beautiful exotic betta fish.

Some believe that it was named after the comic book character "Hellboy" due to its dominant body color. The Hellboy betta fish is also known as the comb tail betta fish and is a very popular and sought-after fish.


The Hellboy halfmoon betta is a short-finned, velvet red fighting fish with blue scales and orange fins. They are mostly bred in tanks, although they originate from Thailand. They may now be found in a variety of locations throughout the world.


These are standard betta fish. The average adult size of a hellboy betta is 2 - 3 inches (5 - 7.6 cm), with the females being slightly smaller than the males.


The lifespan of the Hellboy halfmoon plakat betta is 3-4 years. It can live even longer under proper care, up to 5 years.

Appearance and Behavior:

The betta fish is known for its beautiful fins, which are often more vibrant on male fish, while female fish have shorter fins that may not reach the length of their males. compared to males, the female bettas have darker coloration.

They have a long, thin body that can be wavy or straight, depending on their mood. They often have what appears to be a bluish tinge on the fins and tail, but their body is mostly a red color. Their dorsal fin is large and sticks straight up and then gently sweeps back down into a long caudal (tail) fin.

They have strong jaws with small teeth ideal for eating brine shrimp, bloodworms or daphnia. Bettas are known to be very easy to care for, but they should still be monitored closely as they are known to be jumpers.

Hellboy Betta Care Basics

A single Hellboy halfmoon betta requires a 2-gallon tank. A 10-gallon aquarium, on the other hand, is required to house two of these fish. Unlike other bettas, Hellboy bettas do not get as big as their aquarium.

If you provide them with adequate room, they will stay tiny and manageable for many years without growing stunted or aggressive. Bettas are labyrinth fish, which means they take atmospheric oxygen from the surface of the water like other fishes. In order to keep your betta healthy, the following water conditions are necessary:

Tank Size (minimum):

2 gallons (although they grow tiny the bigger tank is better)

Water Temperature:


pH level:

6.5 – 7.5

These are tropical fish and are known to originate from Thailand and are known to live in warm water, but they can also survive at room temperature. These fish tend to stay closer to the top level of the tank and need open space for swimming. It is very important to note that for this fish, low water flow is necessary so avoid keeping them with filters that produce a strong current.

How Often Must I Change the Water?

You should clean your aquarium once every two weeks with a gravel cleaner to remove waste and uneaten food. If you use tap water, be sure it's been dechlorinated as chlorine can be harmful to fish. When you're changing the water, keep in mind that only 20-25% of the tank's water should be replaced.

 They are sensitive to water chemistry and temperature changes, which is why performing all of the tank at once is not a good idea because it would put a lot of strain on them.

How to Decorate a Hellboy Betta Fish Tank?

This Betta is relatively undemanding as far as care goes. Since they are not very active, it doesn't really matter what kind of decoration you use in the tank. However, the tank must consist of a few hiding places to give your betta fish somewhere safe to rest.

Rocks, driftwood, flowerpots and other non-toxic ornaments are ideal. Use non-toxic aquarium silicone to secure them in place. They may not spend much time in these areas, but they need them to feel secure. You may also wish to provide plants in the tank, although this is not necessary for keeping your fish healthy.

Plant decorations may be soothing for you and your fish, but avoid rough plastic plants that will injure your betta if it jumps into the plant or tries to take refuge inside it. These fish are jumpers and can easily leap from their tank. So, keep the tank covered with a hood or have an aquarium lid.

What kind of tank mates would be appropriate for Hellboy betta?

Hellboy betta fish can be kept with other non-aggressive species that have a similar water temperature. Avoid keeping them with fish that might nip at their fins or those that are larger than the Betta. Female bettas can be put together as long as the tank is appropriately sized.

On the other hand, Male Bettas cannot be kept with other betta species, as they are aggressive fighting fish that may fight for dominance and territory. However, they can be kept in a community tank, with other non-aggressive fish that have a similar water temperature such as: -

Corydora- Also called as Cory Catfish, they are bottom-dwelling scavengers. You can keep 5 or 6 catfish in a 10-gallon aquarium, which makes it the perfect tank mate for your betta fish. The soft sand substrate helps to bring out their natural behaviors which include exploring and digging.

Guppies- These are beautiful, colorful and lively fish. Guppies come in a variety of different colors and patterns that would be a great addition to your tank. They are small and easy to care for, making them perfect for beginners. Plus, they are inexpensive and readily available.

Mollies- Another exciting and colorful fish, these can be kept with your betta as long as they are the same size. Although molly fish must have a tropical tank, they can survive in warmer waters unlike most other types of freshwater aquarium fish.

Rasboras- These are beautiful, peaceful and easy to care for fish. They are bottom feeders and come in different colors such as black, orange, blue silver and red. They are an excellent choice to put in your tank with your betta fish because they are very unlikely to nip at your Betta's fins.

Tetras- Tetras are very active and colorful fish that can be kept in schools of 6 or more. They are one of the most popular choices for beginners because they're small, inexpensive and come in a multitude of different colors. Plus, they're relatively peaceful making them the perfect tank mates for your Betta fish.

Zebra SnailsThese are also known as Freshwater Nerite Snails. They are peaceful and very efficient snail cleaners, making them a great tank mate for your betta fish.

African Dwarf FrogsThese are yet another common choice for a freshwater aquarium. These unusual animals are extremely active, so they'll keep your betta occupied all day long.

Ghost Shrimp- As for invertebrates, ghost shrimp are the best to have in your tank with your betta fish. These are bottom-dwelling scavengers that tend to come out at night. They may also be eaten by your Betta, so keep a close eye on them when you notice that your betta is stomach-in.

Because they are Carnivorous, these fish need a varied diet to maintain good health and coloration. They are not picky eaters, but they do prefer their meals live. It is best to feed them foods that are rich in proteins and Omega 3s.

 It can be either fresh, freeze-dried, or frozen foods. If you enjoy petting bettas, you should understand the feeding guidelines for what to feed them, how to feed them, when to feed them, and how much to feed them.

What Can I Feed My Hellboy Betta?

  • Live FoodsThey are the best foods to feed your betta. Feed them daphnia, bloodworms, brine shrimp or mosquito larvae. Bloodworms are a Betta favorite and an excellent source of dietary protein. Daphnia are also another excellent choice because they are easy to culture in your own home. Brine shrimp and mosquito larvae are also easy to culture, but are not as nutritious as the other two.
  • Frozen Foods- These are another good source of protein for your betta fish. Although frozen food is not as nutrient-rich as live food, they are still a good choice because bettas can easily digest them. Frozen brine shrimp is a particularly nutritious food that has plenty of protein, Omega 3s and other nutrients that your Betta needs. However, it is best to soak them in tank water for about 20 minutes before feeding them to your fish.
  • Crustaceans- In general, any small crustacean that you find in the local pet store works great as a treat for your betta fish. Crabs and shrimp are perfect choices for this purpose.
  • Minced meat- You can buy minced beef or chicken from your local grocery store and feed it to your betta fish as a treat. This type of foods is rich in proteins and fats to give your betta energy.
  • Plankton- This is another type of food that you can feed your Betta, which is rich in proteins and Omega 3s. You can buy dried planktons from the pet store or grind up fresh seaweed found at the local beach.
  • Vegetables- Low in proteins, but rich in fibre, vegetables such as cucumber and zucchini make a good choice of food for your Betta fish. You can either chop them into bite-sized pieces or simply place them directly inside the tank.
  • Flake food- This type of food can make a good staple source of nutrition for your Betta. Flake foods are rich in proteins and contain some fats and Omega 3s.

When to Feed Your Hellboy Betta?

Bettas can go long periods of time without food, so don't worry too much about not feeding your fish for a few days. However, it's best to feed them at least once a day. Feeding them during the morning and late afternoon is recommended to give them enough daylight time to digest their meals.

How Do I Feed My Hellboy Betta?

Some people prefer to place the food directly into the betta's tank, while others like to use feeding tongs. There is no wrong way of feeding them and you should do whatever you're comfortable with.

How Much Food Should I Feed My Hellboy Betta?

Hellboy bettas are not picky eaters, but with all this said it's still important to monitor the amount of food you give them. You should also keep in mind that betta fish often eat their prey in two separate meals because they prefer to swallow their food without chewing it at first.

This is why it's important to feed your betta fish small portions of food throughout the day. Overfeeding your fish can be very harmful to their health and cause serious water quality problems. A good rule of thumb is to feed them only what they can eat in about 5 minutes. It is very important to remove any uneaten food from the tank to avoid water fouling.

Diseases in Hellboy Betta Fish

Hellboy Betta, like other fish, can fall sick. However, there is no need to panic because most of the time, they will be able to fight off any infection if their environment is clean and maintained well. The very first thing you should do when a fish becomes sick is to check on its environment.

All the equipment in your tank should be working properly. It is also important that you keep a close eye on your water quality to ensure that it is within the acceptable range. If these factors are in order, then all you have to do is monitor your fish for any signs of infection.

The Most Common Diseases in Betta Fish Include: -

  • Fin rot- This is a bacterial infection that usually starts with the fins. At first, you might notice slight discoloration on the tips of your Betta's fins. As the disease progresses, it will eat away at the fins and cause them to disappear completely. Fin rot can be treated with antibiotics, but it is best to begin treatment as soon as possible.
  • Dropsy- A betta fish with dropsy has visibly swollen scales. This is caused by an internal bacterial infection that damages the liver and kidneys, which then results in fluid retention within the body cavity. Dropsy is very serious because it can be fatal if left untreated. Your Betta might recover from this disease, but you will most likely lose it in the process.
  • Popeye- This disease happens when an infection damage one or both of your betta fish's eyes, causing them to swell and protrude from their head. While this might be alarming to look at, Popeye is easily treatable with antibiotics. It is best to consult a veterinarian for proper medication and dosage.
  • SD-SD stands for 'swim disease' and it prevents your betta fish from maintaining its buoyancy. A fish with SD will sink to the bottom of the tank no matter how much you try to make it swim. Fortunately, there is a medication that can fix this problem and it usually resolves in around ten days.
  • White spot- This is a parasitic infection caused by tiny bugs called 'Ich'. It starts out as small white spots on your betta fish's skin and fins, which eventually spread all over its body. White spot can be treated with a specific medication and it will usually go away in around ten days.

Sick Hellboy Betta Symptoms

There are a number of signs that could indicate a problem with your betta fish, including rapid breathing and clamped fins. However, the most common sign of a sick betta is a change in color coloration. The colors on a healthy betta fish are bright and vibrant, but a sick Betta may have pale colors, dark spots or blotches.

Symptoms of Shininess in Hellboy Betta

Many betta keepers believe that shiny, vibrant fins indicate healthy and happy betta fish. In most cases, this might have been true, but there are a few instances in which the opposite is true.

Shiny and vibrant Hellboy Betta fins can be a sign of a potentially life-threatening bacterial infection called ‘Velvet'. This disease is caused by microscopic parasites that break open capillaries with their teeth and cause erythropoiesis (a reddening of the skin) and hemolymph release. Velvet is very difficult to diagnose, so it is usually identified during a necropsy.

Dragon scale bettas have a beautiful, shiny and glossy sheen to their bodies. However, this is not an indication of illness. These are relatively new variety of betta fish that is gaining in popularity. 

Hellboy Betta Breeding Care

Bettas can be bred in the same manner as other betta Splendens fish. In order to breed the betta fish, it is very important to ensure that the tank water is of high quality and clean. The ph., hardness and nitrates should be within the appropriate range.

There should not be any parasites present in the tank. Breeding tank must be set up in such a way that there should not be anything lying on the bottom of the tank so that the eggs laid by the female Betta fish should not get attached to it.

Tips On Selecting Perfect Breeding Pair

The age and size of the breeding pair must be taken into account while selecting the best breeding pair. Breeding is usually successful if both the male and female bettas are of same age and size. Selection of healthy male is important for breeding purpose because if the male betta fish is weak then it may not be able to compete with the female in order to fertilize the eggs.

Behavioral Changes During Breeding

In open waters, they usually breed in spring or autumn season when the water temperature is ideal for them to breed. However, in aquariums, betta fish can breed throughout the year unless there are any changes in the water temperature. The behavior of betta fish such as darkening of color and change in eating habit must be observed while keeping them for breeding purpose.

Breeding Procedure

Hellboy betta like any other betta fish, breed in bubble nests. Once the bubble nest is ready the male betta fish then starts showing a courtship behavior towards the female betta fish. Female fish eventually accepts the male betta fish, and they start spawning.

The male Betta fish then fertilize the eggs while they are released into the bubble nests. It usually takes around 24 hours for the eggs to get fertilized. It is often better to transfer the female betta fish to another aquarium after the spawning to avoid any issues with male betta fish.

It's not uncommon for female fish to try to consume the eggs. It's also true for male betta fish, though it happens less frequently. After fertilizing the eggs, move him to another tank so as to avoid any such problems.

How Long Do Hellboy Betta Eggs Take to Hatch?

The eggs can hatch anytime between 36 hours-3days. The exact timeframe will depend on the water temperature and the quality of the water.

Betta Fry Care

The newly born betta fish are not able to survive in water and they need long-term care. The best way to provide them suitable condition is by using a separate tank for them. This separate tank should be provided with aeration system, heater and filter.

 The temperature of the tank should be maintained around 80–86-degree F. Ph level of the water should be maintained around 7.6-7.8 and the water hardness around 10-20 ppm. The tank must have some soft live plants like java moss or baby tears to provide them break from constant current of the filter.

Betta Fry Feeding 

Small size Betta fry usually feed on infusoria which is a type of zooplankton that's found in water. Infusoria can be cultivated by keeping a piece of boiled spinach or lettuce under a strong light for about 24-48 hours. Betta fry can also be feed with micro worms as a first food and then followed by newly hatched brine shrimp.
