Nope, I want something new. My convicts seem to be fine on their own tank right now. However I will consider to move them if they getting a little bit bigger.
Well, I have a kenyi right now. I don't know if you know anything about them, but from what i've heard and seen the girls are blue and the boys are yellow. Now if i'm wrong someone correct me. And they are a little aggressive. But their so stinking adorable. That's my suggestion.
It would be ok if you got a silver arowana but only if you got it as a baby. They grow one inch for every month in the first year of there life. So for a grow up tank yeah but you couldn't keep him in there forever.
