I have a pictus catfish in a 45 gallon. I have heard that this is too small. As of right now he is maybe 2 inches? He is in a tank with 2 platys, 6 black neon tetras, 1, 2 inch? Rt shark, a gold gourami and 8 kuhlis. *I am hoping to get a 75 soon for my rt shark so don't worry.* I have heard all sorts of differ t things about pictus cats. What size tank do they need to be in, how big do they get, do they need to be in schools, and is he eating my black neons, as two have gone missing. And lastly, do I need to rehomed him?
