Tank mate check
Can Discus and Goldfish live together?
Verdict: No
No. Discus and Goldfish 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.
- Both species are peaceful. Discus is rated peaceful, Goldfish peaceful.
- No temperature overlap (82-88°F vs 65-72°F).
- pH overlap 6.5 is a narrow band, so hold pH steady inside it.
- Goldfish may not be compatible with Discus.
- 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.
