How big does a rummynose tetra get?
A rummynose tetra (Hemigrammus rhodostomus) reaches about 2.0 inches as an adult. Plan tank size and tank mates around the adult size, not the small fish you buy at the store.
Tank size & setup
Give a rummynose tetra a minimum of 20 gallons, with water at 75–84°F and a pH of 5.5–7. Keep them in groups of at least 8 — they are shoaling fish and become stressed and washed-out alone. As a moderate-care, omnivore species, a stable, cycled tank with the right diet keeps them healthiest.
Good tank mates
Pair a rummynose tetra with peaceful species that share its temperature and pH range. Compatible options include:
- Neon Tetra — 1.5", 10g min
- Guppy — 2.0", 10g min
- Molly — 4.0", 20g min
- Platy — 2.5", 10g min
- Zebra Danio — 2.0", 10g min
