Can Blue Gourami live with Green Neon Tetra?
Not recommended
Why
- Blue Gourami’s mouth is big enough to swallow Green Neon Tetra (only 1" long) — it will be eaten.
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
- Blue Gourami is semi-aggressive — give the peaceful Green Neon Tetra plenty of space, cover and broken sight lines.
