A suitable tank for celestial pearl danios is one that is large enough to give them plenty of room to swim, with consistent water temperature, ph levels, and hardness. The filtration and aeration should be set up in a way that provides a gentle current, while the tank decorations and substrate should replicate their natural habitat.
