Can Black Neon Tetra live with Opaline Gourami?
Caution — with care
Why
- Opaline Gourami may eat Black Neon Tetra; add only full-grown adults, because juveniles and fry will be picked off.
- Opaline Gourami is semi-aggressive — give the peaceful Black Neon Tetra plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–82°F and pH 6–7.5 — aim there.
