I might just try it for a while, I like the jardini a lot, it's not just a test for my channa. It's costing a lot more than the channa too.
Thing is, my channa is a VICIOUS little bastard, but he is little. So he would not be able to kill the aro outright. The SH is pushing 5 inches, and is much fatter than when I got him, but still relatively slim.
The jardini is at least 6 inches and I'm sure weighs a fair bit more.
The little channa has killed a fair few fish the same size as him, though for some reason the convict and texas are still alive and well in there. He chases them around but they are smart enough to keep running until he stops.
If he terrorizes the jardini and it looks like the jardini can't handle it I'll put a divider up, then cycle a new tank for the aro. I don't want either fish to die, I like them both a lot, and it would be cool if they lived together for a while.
I'm getting it tomorrow morning but I'm undecided of whether to introduce the aro immediately, or put him in a divided section until he's settled in, and not stressed from the move, then remove the divider.
It may be fine putting him right away, but I'm worried that it might be a bit much after transporting him if the first thing he is faced with is a pugnacious little channa in his face.
