I just got Buster last week. Someone I know gave him away to me. He wasn't very well taken care of though. He was in a 1 gallon tank with no filter or lights and they were feeding him flakes, etc. I switched him to a 2.5 gallon tank with all the fixings and he seems much happier now. He didn't eat for the first few days which I've learned is normal. But now he is a pig! haha. He always wants to eat.
Here's a picture of Buster. He stares at me like this whenever I walk by because he thinks I'm gonna feed him
2.5 gallons isn't exactly ideal, so I'm hoping to get him a 5 gallon soon.
