Why do they sell these shark catfish? Who has a tank large enough for these? I guess they are called Pangasids or Paroon sharks. I got these with a tank that I bought but they started eating the shrimp for the Aro and every other kind of food that I put in the tank including algae wafers for the Plecs. Maybe it's just me but I don't want some insatiable catfish with a balloon belly taking over my tank. Heres the beast! I got 2 of these.
