Can Green Neon Tetra live with Green Tiger Barb?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 4–5 dGH.
- Green Tiger Barb is semi-aggressive — give the peaceful Green Neon Tetra plenty of space, cover and broken sight lines.
- Large size gap (Green Tiger Barb 2.75" vs Green Neon Tetra 1") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–82°F and pH 6–6.5 — aim there.

How to make it work
