Can Moonlight Gourami live with Neon Tetra?
Caution — with care
Why
- Moonlight Gourami may eat Neon Tetra; add only full-grown adults, because juveniles and fry will be picked off.
- Only a narrow temperature overlap — keep both around 77–78°F.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
Sweet spot: both do well at 77–78°F and pH 6.5–7 — aim there.
