Compatibility brief
Can Denisons Barb live with Neon Tetra?
Caution. Check the issues below before buying.
Denisons Barb + Neon Tetra: Caution advised. Denisons are large active shoalers that need cool water (18 to 25 C) and 120 cm of length. Neons want 22 to 27 C. The temperature overlap is narrow, the speed difference unsettles the neon school, and the tank size that holds denisons rarely suits nano tetras. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
