This is my newest cat, it's a sun catfish and yeah that's a home depot bucket and it fills the bottom completely. It's the biggest one I've ever seen. I have to acclimate it then I'll add it to the 55 temporarily until the 125 is up and running.
So far their doing well. Neither of then have eaten anything yet but I think once they get hungry enough they will. I had to move the sun cat to my 20h hospital tank cause I noticed a fresh gash on it's side. I think that trying to adjust to it's new tank it may have hurt itself on some driftwood so I'm gonna treat it in the smaller tank.
