Loach Catfish – Everything You Need to Know About Keeping These Lovely Fish

Catfish are becoming increasingly popular as pets, and for good reason! They're unique, interesting creatures that are relatively easy to care for. There are many different species of catfish, and loach catfish is one among them.

Loach Catfish are found throughout Asia: Northern Peninsular Malaysia, Thailand, and Cambodia. They are most common at high elevations, where the majority of species can cling to rocks in swiftly flowing streams. These small catfishes with tapering, elongated bodies have large pectoral and ventral fins and the first ray of each is usually broad, flexible, and filamentous.

If you're thinking about getting a loach catfish, or if you already have one, read on for everything you need to know about their care!

Loach Catfish Appearance

Amblyceps, or catfish, is notable for having the epiphyseal commissure of the supraorbital sensory canals immediately anterior to, but not passing through the epiphyseal bar. The posterior fontanelle gradually narrows at its rear end, providing bony support from the front via the epiphyseal bar to the rear for the nuchal ligament.

The body shape of a loach catfish is long and slender, with a large head and wide mouth. They have two pairs of barbels on their upper jaw and one pair on their lower jaw. These barbels are used to help them find food in murky water. They have large, round eyes, and their bodies are covered in smooth scales.

The posterior end of the ceratobranchial is expanded medially, although there are pinnate-like rays along the anterior margin of the current and medial caudal-fin rays, a transverse crest along the whole posterior margin of the roof of the supraoccipital and pterotic, as well as an anteroposterior crest on the epioccipital.

The nostrils are tiny and widely spaced, with the upper hypural fused to the compound centrum, the anterior nostril positioned immediately adjacent to the base of the nasal barbel, and double folds on both lips. It also has a prominent cup-like skin flap above the pectoral spine's base.

Gender Differences

  • Both genders are comparable, although males are generally more slender than females who get visibly hefty when stuffed with eggs.
  • Males may have a red glow around their barbels, too.

Loach Catfish Behavior 

Loach catfish are peaceful species of fish that do well in community tanks. They are relatively active and love to explore their surroundings. They are also known to be very social creatures and enjoy being around other fish. It's a good idea to keep them in groups of 3 or more so they feel comfortable and secure in their environment.

They are very shy fish and will often hide when they feel scared or threatened. It's important to provide them with plenty of hiding places in their tank so they can feel safe and secure. Plants, caves, and other decorations are all good options.

Loach Catfish Tank setup

Setting up a proper tank for your loach catfish is essential to their health and well-being. There are a few things you need to take into consideration when setting up their tank:

  • Tank size: The minimum tank size for loach catfish is 40 gallons, but the larger the better. They are active fish that love to explore their surroundings, so a larger tank will give them more room to swim and play.
  • Water Parameters: It's important to maintain good water quality in their tank. Loach catfish are sensitive to changes in water quality and can get sick easily if the water is not clean and well-oxygenated. The ideal water temperature for loach catfish is 75-85 degrees Fahrenheit (24-29 degrees Celsius). The ideal pH level for their tank is 6.0-7.5.
  • Substrate: The best substrate for loach catfish is a sandy bottom. This will help keep their barbels clean and prevent them from getting damaged. Examples of good substrates include gravel, sand, and clay.
  • Plants: Loach catfish love to hide in plants, so it's a good idea to include some in their tank. They also help oxygenate the water and provide shelter for your fish. Some examples of good plants for their tank include Java Fern, Anubias, and Hornwort. If you don't want to use real plants, you can also use plastic plants. However, make
  • Other decorations: It's a good idea to include other decorations in their tank for them to explore and hide in. Caves, rocks, and driftwood are all good options.
  • Filter: It's important to have a good filter in their tank to keep the water clean and well-oxygenated. A canister filter is a good option for their tank.
  • Lightening: Loach catfish don't need strong lighting, so a simple fluorescent light will suffice. Some plants may require more light, so you may need to increase the lighting if you have live plants in their tank.

Tank Maintainance 

It's important to regularly maintain their tank to keep the water clean and the fish healthy.

  • Water changes: It's important to do a partial water change of 10-15% every week. This will help remove any toxins that have built up in the water and keep the water quality high.
  • Cleaning the substrate: It's important to clean the substrate regularly to prevent it from becoming too dirty. A good way to do this is to vacuum it with a gravel vacuum every week during your water change.
  • Cleaning the filter: It's important to clean the filter regularly to prevent it from becoming clogged and inefficient. A good way to clean it is to rinse it in old tank water every other week.

Note: Before adding the new water to their tank, be sure to dechlorinate it to remove any harmful chemicals. You can do this by using a water conditioner or letting the water sit out for 24 hours.

Loach Catfish Tank Mates

Loach catfish are peaceful beautiful fish that do well with other peaceful fish. Some good tank mates for them include:

  • Bala Sharks
  • Tiger Barbs
  • Gouramis
  • Danios
  • Rasboras
  • Cory Catfish
  • Tetras
  • Rainbowfish

It's best to avoid keeping them with fish that are too small, as they may be mistaken for food and eaten. Also, avoid keeping them with any aggressive fish, as they may bully and harass the loach catfish.

Some fish that are not recommended as tank mates for them include:

  • Bettas
  • Goldfish
  • Angelfish
  • Cichlids

Feeding Loach Catfish Catfish 

Loach catfish are easy to feed and will accept most types of food. They are omnivorous, so they will eat both plants and meat. Some good options for their diet include:

  • Pellets: Loach catfish pellets are a good option for their diet. They contain all the nutrients your fish need to stay healthy. While selecting a pellet food, make sure to choose one that is specifically for loach catfish or bottom-dwelling fish.
  • Flakes: Fish flakes are another good option for their diet. They are easy to find and contain a variety of nutrients that your fish need. Again, make sure to choose a flake food that is specifically for loach catfish or bottom-dwelling fish.
  • Live food: Loach catfish also like to eat live food, such as brine shrimp, bloodworms, and daphnia. Live food is a good way to add variety to their diet and it's also a good source of protein. However make sure not to overfeed them live food, as it can dirty their tank quickly.
  • Vegetables: Loach catfish also like to eat vegetables, such as zucchini, cucumber, and lettuce. Vegetables are a good source of vitamins and minerals for your fish. You can either feed them raw vegetables or blanched vegetables.

Feeding Tips to Remember 

  • Be sure to feed them small amounts of food several times a day, rather than one large meal. This will help prevent them from getting overweight and will also help keep their tank clean.
  • Do not overfeed them, as this can dirty their tank quickly and lead to health problems. Only feed them as much as they can eat in a few minutes.
  • If you are having trouble getting your loach catfish to eat, try feeding them live food or frozen food. This will usually entice them to start eating.
  • Always remember to remove the uneaten food from their tank, as this can dirty their water and lead to health problems.
