Fish for a 10 gallon tank

43 fish and 15 shrimp, snails or frogs fit a 10 gallon tank as adults. Ten gallons opens up small schooling fish, pygmy corydoras and livebearers; pick one or two schools plus a centerpiece or bottom group, not one of everything.

A species fits when its adult group fits this size of tank. Together they still have to share water and temperament: check your mix in the stocking checker.

Scroll sideways to see them all. All drawn at one scale, adult size: = 1 inch. Tap one to open its care page.
