Fish Profiles

Welcome to our Species Profile page. The idea behind this page is to share information on various fish species. This section will be a work in progress and ever evolving. Please be patient and keep checking back for regular updates.

Family Auchenipteridae – The Woodcats

The first group we wish to share are the Auchenipteridae or the woodcatfish. Woodcatfish are now gaining in popularity and rightfully so! We do believe they deserve to even be more popular. That is why we will be sharing more information on them.

Woodcatfish or woodcats for short, have many interesting habits such as feeding and special anatomy that no other catfish to date share. They typically feed throughout the tank especially at the surface. They will cruise around almost like torpedoes! Woodcats are also the only catfish family known to practice internal fertilization. With their many color patterns, these fish have a lot to offer.

Many of the species AmazonTropics carries remain 4″ or less. This means you may keep them in small aquariums of 10-30 gallons. Your source water should not be too hard and soft water used for breeding. Outfit the aquarium with a sponge filter or hang on the back filter. Use a small heater to keep temperatures around 74-78 F. Decorate the tank with a thin layer of sand, river rock and driftwood.¬† Be sure to provide areas for these fish to hide as they are nocturnal. Lighting only needs to be secondary with subdued light. For their diet, feed woodcats foods like brine shrimp, bloodworms, water fleas, flakes and pellets.
