Can Betta Fish Live With Black Skirt Tetra?
No, black skirt tetras are known fin nippers and will damage a betta's flowing fins in a matter of days.
Why
- Black skirt tetras grow to 2.5 inches and are active swimmers that naturally nip at long-finned tankmates.
- Black skirt tetras kept in schools of 6 or more become bolder and more coordinated in their nipping behavior.
- A betta's long fins are an easy target and the tetras will repeatedly attack the trailing edges.
- Once fins are damaged, the betta becomes vulnerable to secondary bacterial infections.
What could go wrong
Within 48 hours of introduction, black skirt tetras will tear the betta's fins to ragged edges, leaving permanent damage.

Better pairings to consider
Black skirt tetras do well with barbs or danios that can outswim them. Bettas do well with nerite snails or bristlenose plecos.
