Choppers alone in the tank right now. I just got a small albino tiger oscar the other day, but he's only about a inch and a half, maybe 2 at the most. Figured Chopper would eat it before he even took the time to see what it was

I planned on asking if they could share a tank together down the road, but I don't know if the two O's need to be close to the same size? and I'd definetely need a bigger tank if they were to live together.

Later I'll probally have a million questions about the plus and minuses of them sharing a tank, but I figure I've got some time before it would even be viable (not to mention before I could afford a big enough tank ).

Should I still get a flat rock for the tank? will it make him more comfortable to go through the motions?
