A sun cat/eclipse cat maxes out at 8-10 inches and are gorgeous, a lace fin sydontis maxes out at 6 and is pretty with less color. Never had a tonof luck with pims, but they are energetic, but if something fits in their mouth its as good as gone.
Farawella cats get to about 12 and are neat looking.
Theres always the option of a school of corys. The lazer corys ive been seeing lately are drop dead gorgeous.
Good idea! My thoughts exactly! You can get like 3 eclipse cats in a 75. Or you can get like 40 cory cats but that would be a waste basically as they mostly hide. I have 5 and they are constantly hiding
