Colombian Shark Catfish

General information

Ariopsis seemanni requires a very large tank due to its size and active swimming habits of this fish, they grow up to 20″ in length. While at the pet store they are typically found in the freshwater fish section they are actually a brackish water fish that starts off in freshwater and migrates to saltier waters. As it matures needs to be acclimated from freshwater to saltwater to mimic its natural habitat. This makes this species a good fit for a species-specific tank to allow for you to adjust to its needs without affecting other species.

They normally accept most fish foods including flakes, frozen, freeze-dried and live foods. As they get larger they will eat anything that fits in their mouth including other tank mates.

As Ariopsis seemanni get larger they will eat smaller tank mates so make sure to choose proper tank mates.

Colombian Sharks also have venomous dorsal spines, so be very careful when performing your tank maintenance. When performing maintenance on your tank it is suggested to wear long rubber aquarium gloves.
