Tank mate check
Can Betta Fish and Discus live together?
Verdict: No
No. Betta Fish and Discus fail at least one check below, so keep them in separate tanks.
Why
The same temperament, water and known-conflict checks the MyAquaLog compatibility tool runs.
- Semi-aggressive species may stress peaceful fish. Betta Fish is rated semi-aggressive, Discus peaceful.
- Temperature overlap 82°F is too narrow.
- pH overlap 6.5 is a narrow band, so hold pH steady inside it.
- Discus sets the floor at 50 gallons on its own. Size up from there for both groups.
- Keep Discus in a group of 4 or more.
