I have a 1 gallon tank. I put a large goldfish, a black molly and a dalmatian molly in there. I'm not sure if the color is a difference in how aggressive they are, but that dalmatian molly keeps nipping at the other fish!! i think it has nearly killed the molly, and I can see where the big goldfish is raw-looking on the side (i don't recall it being pink, he was white!)
With that being said, i'm getting a 5 gallon so I can put my goldfish in there with (if it lives long enough) the other molly. But my dalmatian molly will not be invited. I don't want to waste the small tank on just him- can i put a betta in with him (male, i would like a colorful one)? I would say he's aggressive enough!!??
