Can Betta Fish Live With Lemon Tetra?
No, lemon tetras are peaceful but compete with bettas for space, and bettas often attack them as intruders.
Why
- Lemon tetras reach 2 inches and school in the mid-level, directly overlapping with a betta's preferred zone.
- Bettas are territorial and view any mid-level swimmer as a threat to their space, especially in smaller tanks.
- Lemon tetras kept in groups of 6 or more may band together defensively, which can further provoke a betta.
- The stress of a betta chasing them causes lemon tetras to lose color and stop schooling normally.
What could go wrong
The betta relentlessly pursues the lemon tetras until they hide behind plants or decorations constantly, then may injure them when cornered.
