Can Black Molly live with Tiger Barb?
Caution — with care
Why
- Tiger Barb is semi-aggressive and may bully the peaceful Black Molly — give lots of space and cover.
- Tiger Barb is a fin-nipper and will shred the long/flowing fins of Black Molly.
Sweet spot: both do well at 74–82°F and pH 7–8 — aim there.

How to make it work
- 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.
