A friend of mine has picked up for me an African Butterfly (Pantodon buchholzi), which I've wanted for a long time. For the past couple of weeks, I've had two Golden Wonder Killifish (Aplocheilus Lineatus) in a quarantine tank, waiting to move them into my 90 gallon tank-but that's where the butterfly is headed. I know they're both surface dwellers, so will it be asking for trouble to put these fish together?
