tankmate
Fish bowl buddy
A tankmate is a fish or other aquatic creature that shares an aquarium with another.
The term appears most often in discussions of compatibility—whether species can coexist peacefully: Bettas are aggressive and need careful tankmate selection.
Aquarium hobbyists research which fish make good tankmates before adding them to an established tank.
