Can Green Neon Tetra live with Three Spot / Blue Gourami?
Not recommended
Why
- Three Spot / 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.
- Three Spot / Blue Gourami is semi-aggressive and may bully the peaceful Green Neon Tetra — give lots of space and cover.
