Ok so I've got 4 LDA72's in a 55 only had them for a month or so. Don't know what I've got as far as male female so I don't know if they will ever breed or not. Anyway my question is can I put some other fish in this tank or will that further inhibit the chances of them breeding. I'd just like to put some dithers in there so I see something swimming around rather than having it look like an empty tank. Any suggestions?
