5 adult Mountain Redbelly Dace in breeding condition. Just put a bowl full of nickel to quarter size rocks in a lower flow area. These are absolutely beautiful fish. No heater needed, room temperatures are great. Love current, see my lot 1817 stream tank, check link in comments of that auction to see stream tank with juvies, can't give them too much flow. Do well in aquarium don't need super fast flow but need clean well aerated water. Don't bother anything they can't fit into their mouth and they have a small mouth. Take flake, frozen basically anything.
