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 dGH.
- Blue Gourami is semi-aggressive and may bully the peaceful Green Neon Tetra — give lots of space and cover.
