Corydoras Robustus: the Perfect Low-maintenance Addition to Your Aquarium

Corydoras are a popular type of armored catfish amongst fish keepers. They are desired for their pleasant demeanor and ability to coexist with other fish. Corydoras originate from South America and can be found in the Amazon River Basin spanning Peru, Bolivia, and Brazil. There is great diversity between species of Corydoras including coloration and patterning. One particularly well-known variety is Corydoras Robustus.

The Corydoras Robustus is similar in shape to other Corydoras, but with a slightly longer dorsal fin. This fish's base color is cream-copper with small dark brown spots on its sides. There is also a black band that runs from the dorsal fin to the eye, intersecting with a gold band. They are peaceful and social fish, doing well in groups of their own species or mixed with other small, peaceful fish. Corydoras Robustus is also known for being very low-maintenance, making them a great addition to any aquarium.

In this article, we shall discuss everything you need to know about Corydoras Robustus, including their natural habitat, diet, and tank care requirements.

Corydoras Robustus size

Corydoras Robustus fish are relatively small, only measuring 2.0-2.8 inches full grown. They have a bigger tank though, as in one that is at least 30 gallons so they have enough swimming space; therefore a smaller aquarium is not recommended for this species of fish even if it's possible to manage water quality levels.. A good diet and stable water temperature also help these guys reach their maximum size potential, but some credit must be given to genetics too since that plays such an important role in how big (or small) any particular Corydoras Robustus will get.

Corydoras Robustus lifespan

Corydoras Robustus has a lifespan of three to five years. This is typical for most fish, and your Corydoras Robustus can live a long and happy life when provided with the proper care and diet.

Corydoras Robustus Appearance

Corydoras Robustus is a beautiful fish that has a cream-copper base color. Its sides are adorned with small, dark brown spots, and there is a black band that runs from the dorsal fin to the eye. This black band intersects with a gold band, making for a very striking appearance. Corydoras Robustus is a peaceful and social fish, doing well in groups of their own species or mixed with other small, peaceful fish.

These fish species have a typical Corydoras shape, but with a slightly longer dorsal fin. Their barbels are also very long, which they use to help them find food in the water. Corydoras Robustus have both anterior and posterior adhesive discs on their undersides. These discs help the fish to cling to surfaces and keep still in fast-moving waters.

Corydoras Robustus Behavior 

Corydoras Robustus is a peaceful and social fish that does well in groups of their own species or mixed with other small, peaceful fish. They are not known to be aggressive towards tankmates but may bicker amongst themselves if they feel crowded. Corydoras Robustus is also known for being very low-maintenance, making them a great addition to any aquarium.

Corydoras Robustus sometimes form schools in the wild, but this behavior is not often seen in captivity. Schools of Corydoras Robustus are more likely to form if there are other fish present in that school together.

Corydoras Robustus Tank Setup

It's very important to have the correct tank setup for your Corydoras Robustus. If you're a beginner aquarist, setting up a tank may be stressful, but it isn't as difficult as it appears. Follow these measures to ensure a successful tank setup.

Tank Size

Corydoras Robustus fish only grow to be 2.0-2.8 inches, but they need a tank that is at least 30 gallons so they have enough swimming space. A smaller aquarium is not recommended for this species of fish even if it's possible to manage water quality levels.

There are many perks that come with a bigger tank. First, you'll have more space to add other fish or decorations. Second, a bigger tank is easier to maintain because it has more water to dilute toxins. Third, a bigger tank can accommodate more filtration, which is very important for keeping your Corydoras Robustus healthy and happy.

Water Conditions

Corydoras Robustus is very low-maintenance when it comes to water conditions. They can tolerate a wide range of water parameters, but the ideal water temperature for them is 71.6-78.8°F. The pH level should be 6.0-7.5, and the water hardness should be 5-19 dKH.

It's very important to test your water regularly to make sure that these parameters are within the ideal range. Water quality can fluctuate for many reasons, so it's important to be on top of it. The best way to do this is to invest in a good water test kit.

Filtration

Corydoras Robustus is very low-maintenance when it comes to filtration, but it's still important to have a good filter in your aquarium. A canister filter or a hang-on-back filter will work well for this species of fish. Be sure to choose a filter that is rated for an aquarium that is at least twice the size of your tank.

It's also a good idea to invest in a water test kit so you can test your water regularly and make sure that the filter is doing its job.

Tank Decor 

When choosing décor for your Corydoras Robustus tank, keep in mind that these fish are bottom-dwellers. Plants are a wonderful addition to the tank since they will provide hiding places for the fish. Although Corydoras Robustus is not known to be fin nippers, it is possible that they may chew on plants. Make careful when selecting plants because they must be safe for aquarium usage and cannot cause any damage if consumed. Java moss, Anubias, and Echinodorus are all excellent choices.

Driftwood and pebbles may be used to cover the bottom of the aquarium, as well as provide hiding places. Any rocks or driftwood you add must be suitable for aquarium use and will not change the pH of your tank water. Also, make sure that any decorations you choose do not have any sharp or jagged surfaces that could harm the fish.

Corydoras Robustus is a hearty fish that will adapt to a wide range of substrates. A fine gravel or sand substrate is excellent since it allows the fish to dig and burrow if they wish. If you want, you may add a low-wattage aquarium light.

Corydoras Robustus Diet

Corydoras Robustus will happily eat a wide variety of foods. In the wild, their diet consists mostly of insect larvae, small crustaceans, and bits of plants. However, in captivity, they can be given many different types of food such as:

Pellets: There are many different sorts of pellets available that are suitable for Corydoras Robustus. Make certain you get a sinking pellet and one that is small enough for the fish to consume.

Flakes: Although flakes can be fed to Corydoras Robustus, it's best to use them only occasionally as they tend to make the water murky. This is especially true of larger flakes that the fish may have trouble eating.

Frozen/freeze-dried foods: Corydoras Robustus will relish bloodworms, brine shrimp, and daphnia, all of which are excellent food sources. Before feeding frozen goods to your fish, be sure they have been defrosted.

Live foods: You can also feed your Corydoras Robustus live foods, such as blackworms, earthworms, and brine shrimp. Just be careful not to overfeed them—too much food can cause problems like obesity and indigestion.

Vegetables: Corydoras Robustus can also eat veggies like zucchini, cucumber, and peas. Before feeding your fish, blanch or steam the vegetables to ensure a safe meal.

Corydoras Robustus should be fed two to three times a day. Give them only as much food as they can consume in two minutes. If you're not sure how much to feed your fish, err on the side of caution and give them less rather than more.

Overfeeding can lead to issues like obesity and indigestion, both of which can be fatal to fish.

Corydoras Robustus Breeding

The Corydoras Robustus is a fish that can be easily bred in captivity, provided the owner takes care to provide good water quality and recreate the natural environment of the species. Some tips for successful breeding attempts include:

  • Choosing a breeding pair: The first step in breeding Corydoras Robustus is to choose a robust pair that is both healthy and suitable for breeding. Make sure you pick a male and female who are about the same size and age.
  • Conditioning the breeding pair: Once you've chosen a breeding pair, you'll need to condition them. This may be achieved by raising the water temperature to 82 degrees Fahrenheit and feeding them a high-quality diet.
  • The next step is to set up the breeding tank. The tank should be 10 gallons or more, with a sandy bottom. Be sure to add some hiding places for your fish, such as plants or rocks. PH level 6.5 and dGH 3-5 are ideal levels for this type of environment.
  • Adding the breeding pair into the tank: The breeding pair can be added to the tank at any time. You must slowly acclimate the breeding pair to their new surroundings.
  • Spawning: Once the breeding pair is conditioned and the breeding tank is set up, they will be ready to spawn. The female will lay a few hundred eggs, which the male will then fertilize.
  • Caring for the fry: After being fertilized, the eggs will hatch in 5-7 days. Remove the parents from the tank since they might eat the Corydoras Robustus Fry. The fry will require live baby brine shrimp or micro worms to be fed after hatching. Keep water quality high because the fry is very sensitive to changes in water quality. You can start feeding them crushed flakes or pellets once they are approximately three weeks old. At this age, you may also add them to a mixed aquarium at home.
