Tank Size for Banjo Catfish

Banjo Catfish Food & Diet

The Banjo Catfish are omnivores.  They favor live worms at mealtime, but they are not very picky.  Most of their diet should be meaty.  Other options in order of importance are pellets, live food, frozen food, and vegetables.  Flake food should only be given occasionally.  It is important that their food sink to the bottom of the tank.  Banjo Catfish do not eat algae.

Banjo Catfish Tank Setup

Aquarium Filtration

Good aquarium filtration with slow to moderate water flow is good for the Banjo Catfish.  The tank will require frequent partial water changes to keep the nitrogenous waste at a minimum.  Change 20% of the water a week, taking care to clean the sand.  A good filtration system provides constant filtration and aeration.

Aquarium Lights

They do not need very much in terms of aquarium lighting.  In fact, low or dimmed lighting is best.  They are nocturnal and will feed at night.  They tend to be very shy and probably won’t come out if the lights are on.  It’s a good idea to feed them right before you go to bed at night so that the lights will not bother them.

Aquarium Substrate

Sand is a good option for substrate for the Banjo Catfish because they like to burrow.  Sand will be most like their natural habitat.  The sand should be 2 – 3 inches in depth for the best results.

Aquarium Plants and Hardscape 

You will need to keep an eye on your plants if you choose to have a few.  They may tear up the plants to make a bed for breeding or they may uproot them when they bury themselves in the sandy substrate.  They love to have driftwood and rocky caves in order to hide and it imitates their natural environment.  Most of their tank should be pretty sparse.

Breeding Banjo Catfish

They breed in packs in the wild and in pairs in captivity.  Be aware that they produce thousands of eggs at a time, so breeding in an aquarium may not be desirable.  If they do lay eggs, they should be removed from the tank since some of the adults will eat the eggs or the hatched fry.  The eggs will hatch in only 3 days.  The females grow larger and plumper (have a rounded belly) if you are curious if you have a female.

Banjo Catfish Disease

They are not susceptible to any one specific disease.  They are more prone to ammonia poisoning because they stay on the bottom of the tank where ammonia is more concentrated.  It is important to siphon the sand regularly to clean up the ammonia pockets.  If they do contract a disease, there are certain medications they can have because they are scaleless.  These include Pimafix or Permafix.  They should not be treated with potassium permanganate or copper-based medications.

Even though they are hardy and adapt well to most water conditions, you should be checking on them to make sure they are healthy.  Pay attention to their fins and general coloring to see any signs of disease or stress.

Banjo Catfish Tank Mates

Banjo Catfish are not aggressive fish. In fact, they are very peaceful fish. While they are not predatory fish, they will go after smaller invertebrates such as earthworms, shrimp, snails, and crabs.  Anything that is slow-moving.  They will eat their fry if they happen to breed successfully, so the fry should be removed from the tank ASAP.

Compatible Tank Mates for Banjo Catfish

They are compatible with all sizes of fish.  As long as the other fish doesn’t see them as prey, then they will be safe.  Some good tank mate options are Tetras, Pencilfish, Hatchetfish, Corydoras, and even Cichlids.  Neon Tetras are too small, so opt for the larger ones.

Incompatible Tank Mates for Banjo Catfish

Any larger, aggressive fish that would see them as prey.  About the only defense the Banjo Catfish have is their camouflage.

Banjo Catfish and Shrimp 

Banjo Catfish and Shrimp  are not compatible as the Banjo Catfish like to eat shrimp.

Banjo Catfish and Cichlid

Banjo Catfish and Dwarf Cichlids do well together because of their smaller size.  If you choose to house your Banjo Catfish with other cichlids like the African Cichlid, here are some things to consider.  In order to reduce aggression, make sure there are plenty of hiding spots for the catfish.  Also, make sure the cichlids are well fed so they do not have to compete for food.

It is a good idea to check on your Banjo Catfish periodically to make sure the other fish have not been nipping at them or biting them.  Since they spend a lot of their time sedentary and buried, this can happen, even with tank mates that appear to be friendly to them.  Also, make sure they are getting enough to eat if they have fast swimming tank mates.  Since they are scavengers, all of the food could be eaten before it reaches the bottom of the tank.
