Being a cold-water fish, the White Cloud Mountain Minnows can comfortably carry on in an aquarium even if it has no water heater. Having floating plants in the tank will give even more confidence to the fish, which in turn makes their behavior super entertaining. The Lambchop Rasbora fish do not require very soft water, but they do come from a habitat that’s a little on the softer end.
