Betta compatibility checker
A male betta is already locked in below. Add the fish you were about to buy. Danios and tiger barbs nip fins. Other male bettas fight. A 5-gallon heated tank is the floor; a vase is not a tank.
Read the betta profile and the tank-mates note if you want the short list before you run the checker.
| Mix | Call |
|---|---|
| Alone in a heated 5–10 with plants | Yes. This is the default. |
| Nerite or mystery snail | Usually. Watch for fin-nipping at antennae. |
| Cherry shrimp in heavy cover | Maybe. Many males hunt anyway. |
| Danios, tiger barbs, guppies, other males | No. |
