Can Moonlight Gourami live with Tiger Barb?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Tiger Barb is semi-aggressive and may bully the peaceful Moonlight Gourami — give lots of space and cover.
- Tiger Barb is a fin-nipper and will shred the long/flowing fins of Moonlight Gourami.
Sweet spot: both do well at 77–82°F and pH 6.5–7.6 — aim there.

How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
- Keep the nipper in a bigger group (8+) to spread out the nipping, and avoid long-finned tankmates.
