Can Betta Fish Live With Serpae Tetra?
No, serpae tetras are notorious fin nippers that will shred a betta's long fins given any opportunity.
Why
- Serpae tetras have a well-documented reputation for nipping at tankmates, especially those with long flowing fins.
- They are active schoolers that move in groups, overwhelming slower fish with their constant motion.
- A betta's fins are an irresistible target for serpae tetras once they start nipping.
- Fin damage leads to infection and death in bettas kept with persistent nippers.
What could go wrong
The serpae tetras nip the betta's fins until they are shredded and the betta dies from infection or stress.
