VerdictCAUTION

Caution. Check the issues below before buying.

Denison's / red-line torpedo 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.

Denison's / red-line torpedo barb + Neon Tetra — common questions

Can Denison's / red-line torpedo barb live with Neon Tetra?
Yes, if you plan for it. The verdict is CAUTION, which means the pairing works when specific conditions are met, not by default. The first condition: Denison's / red-line torpedo barb should be kept in a group of at least 6 for best health and behaviour.
What tank size do you need for Denison's / red-line torpedo barb and Neon Tetra together?
Plan around 250 litres as the working minimum. That figure comes from each species' published minimum and their group needs, and it assumes adult sizes, not shop sizes.
What's the main risk?
The main constraint comes from a curated keeper note rather than a single mechanical rule. The matching entry under assessment details on this page explains the reasoning and the numbers behind it.
What should you check before buying?
Neon Tetra should be kept in a group of at least 6 for best health and behaviour.
