Can Black Molly live with Black Skirt Tetra?
Caution — with care
Why
- Black Skirt Tetra is semi-aggressive and may bully the peaceful Black Molly — give lots of space and cover.
- Black Skirt Tetra is a fin-nipper and will shred the long/flowing fins of Black Molly.
Sweet spot: both do well at 72–82°F and pH 7–7.5 — aim there.

How to make it work

- Keep the nipper in a bigger group (8+) to spread out the nipping, and avoid long-finned tankmates.
