My friend gave me one of her angel fish. She bought 2 of them, put them in a 2.5 gallon and crazily overfeed them. I mean crazily overfeed, I have no idea what she was thinking. When one of them died, she gave the other one to me. For the 30 mins she had it in a vase to give it to me, the bottom of the vase was filled with about .5cm of food! It actually wasn't this year, but have been about 8 months since I took it. All it needed was a clean tank to get it back into shape. So I took it into my 5.5 gallon that I had in my dorm. After a month or two, I put him in my 55 where he is doing great.
