Frequently asked questions

What fish can live with guppies?

Peaceful species with compatible water needs, enough group space, and no fin-nipping tendency are the best starting point. Corydoras and some small tetras can work when the entire system fits.

Can guppies live with bettas?

Sometimes, but it is not a dependable combination. A betta may chase or bite colorful, long-finned male guppies.
