Sources & confidence (2 species)

These back the Neon Tetra and Bronze Corydoras figures used for this verdict. Each figure is read from the TankStocking species database (v2026.06); below is the care reference behind it and how confident we are in that data. Confidence reflects the source quality, not whether any pairing is safe. Full source list and the welfare model are on the methodology page.

  • Bronze Corydoras Corydoras aeneus — Seriously Fish (seriouslyfish.com/species/corydoras-aeneus) high confidence

Why

No welfare check fires for this pairing: their adult sizes, temperaments, temperature ranges and social needs line up. Keep each in its proper group and give the tank time to mature.

A workable setup: at least 20 US gallons (76 L), with a group of 6+ Neon Tetra and a group of 6+ Bronze Corydoras, in a cycled, planted tank. Test your exact plan below.

      What to watch in the first two weeks

      Compatibility on paper is only a starting point; the first fortnight is where you actually learn how these two get on. Add the established or calmer species first, give the tank a few days, then introduce the other — and keep watching, because the early days reveal more than any chart.

      • Feeding time — watch whether one species muscles the other off the food. A fish that consistently misses meals is the one that quietly fails first.
      • The shy fish — if one species hides constantly, stops eating, or shows clamped fins, the mix is stressing it, regardless of what the verdict says.
      • Just before lights-on and after lights-out — chasing and bullying often happen at the edges of the day when you are not looking. A quick check then tells you a lot.
      • Have a plan B — a divider, a spare cycled tank, or a way to rehome. The keepers who avoid disasters are the ones ready to separate fish at the first real sign of trouble.
      • These two occupy different levels of the tank, so much of the time they simply keep out of each other's way — note whether each is using its own zone or being pushed out of it.

      Common questions

      Can Neon Tetra live with Bronze Corydoras?

      Yes — Neon Tetra and Bronze Corydoras are a workable pairing in a suitable, cycled tank. TankStocking's engine reaches this by checking minimum tank size, group needs, temperature overlap, aggression, predation by size and fin-nipping for this exact pairing.

      What tank size do Neon Tetra and Bronze Corydoras need together?

      Plan for at least 20 US gallons so both species clear their minimum-tank needs, with a group of 6+ Neon Tetra and a group of 6+ Bronze Corydoras. More water and a planted layout with broken sightlines always help.
