For tanks containing white cloud mountain minnow, you can add a smooth and darker colored substrate, as well as fine-leafed plants. Actually, the white cloud mountain minnow is a fish that prefers to hide, but it also likes light currents. This means that it likes moving water.

Yes, the white cloud mountain minnow needs a filter, especially when you are setting up a tank for breeding fish. I don't think the white cloud mountain minnow needs a heater, because these fish will live easier without one.
