This fish likes hard to very hard water, alkilne.
Guppies are one of the easiest of all tropical fish to care for.
The guppy is a live bearer, and will eat it's own young if you do not remove them from the tank. The guppy has changed quite a bit since we first received them from the wild. They have been inbreed to give them a larger size, larger fins, and more striking colors. There is no end to the color variations.
