Redbelly Dace - Aquarium requirements?

What is anybody's recommendation on the minimum aquarium size to house 6-8 southern redbelly dace? And should a powerhead be included?

Thanks,

Curt

I personally wouldn't go smaller than a 20g long. If you want more height, a 29g. You don't need all that much current but a little would be nice.

The bigger the tank the better. I've currently got 7 in a 20 long and a couple dozen in a 75 and there's a big difference in their activity and coloration between the two tanks.
I've noticed the more plants and current I add to the 75 gallon the more colorful they get.

Thanks for the input, Drew. I like your Yogi quote.

Good to know! Thanks.

I would try to keep them in a longer tank. I don't think they'll get much out of a tall tank (at least when I kept them in a 90 gallon and a 135 gallon there was a lot of "wasted space"). If I were just keeping RBD and nothing else in the tank to fill in those other layers, keeping a group of 8 or so, I think a 30 gallon (36" long) would be really nice. A 20 gallon "long" (30") would be doable, also, but I think they would appreciate the extra room a 30 gallon affords.

The places I collect them in always seem to have a good bit of current and shallow depth. Just these little bubbling streams, really, so narrow that you could step over them in most places without getting your feet wet. I usually find them with young creek chubs.

That sounds pretty good. I live in a townhouse so I can't go crazy with tank size.

Thanks.
