Yes, you read that right.
I'm setting up my 44-gallon tall aquarium for a crayfish. I'd like to put in a decent sized group of a single species of small or medium-sized fish that I don't mind getting eaten. I'd prefer a fish that likes to shoal and is relatively attractive. I thought something blackish might look nice. I'll have a light-colored sand substrate and will be experimenting with some plants. Does anyone have a suggestion? If I don't come up with anything better, I'll probably just end up with some guppies or something.
