I Need Help Identifying A Catfish

Hi, i went to a new fish shop recently a purchased 2 beautiful catfish which i was told were silver shark catfish. I have since read some stories regarding the amount of different catfish so now dont have a clue what i have. Can someone tell from these pictures what i have and possibly tell me something about then.

kind regards

They look the same as mine, but when I bought them Pets at Home called them all sorts of things, but we managed to agree on either Aluminium catfish or shark catfish. They need to be kept in Brackish water though.

yes they are shark cats or columbian catfish seems to be a pretty popular name but yeah, as mentioned they do need anywhere between brackish to full marine as adults they should be fine in freshwater until they around 5 inches however.
The bad thing about these guys is that they easily grow to 15 inches but can get up to 24 and will eatabout anything that fits in there mouth. Great fish to keep if you can care for them though!

Yep they're Colombian Shark Catfish

hope you have a big Brackish tank
