Can Green Neon Tetra live with Tiger Barb?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 4–5 dGH.
- Tiger Barb is semi-aggressive and may bully the peaceful Green Neon Tetra — give lots of space and cover.
- Tiger Barb is large enough to threaten a small Green Neon Tetra — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 75–82°F and pH 6–6.5 — aim there.
