Can Discus live with False Rummy Nose Tetra?
Caution — with care
Why
- Almost no shared temperature: Discus wants 82–88°F and False Rummy Nose Tetra wants 75–82°F, so only 82°F suits both — too fine a margin to actually hold.
- Large size gap (Discus 8" vs False Rummy Nose Tetra 2") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 82–82°F and pH 5.5–7 — aim there.
