Overview
Serpae Tetras are deep-bodied, ruby-red tetras with a black comma-shaped mark behind the gills and black-edged fins. They are known fin-nippers, especially when kept in small numbers.

Expert Care Tips for Serpae Tetra
- Mid-size tank: Serpae Tetra needs 20+ gallons. Choose a tank at least 2× as long as the fish's adult size (2.0") for adequate swimming room.
- Tropical range: Keep Serpae Tetra at 72–79°F. A 50W heater per 10 gallons is a safe rule of thumb for stable temperature.
- Adaptable pH range: Serpae Tetra accepts pH 5.5–7.5. Most tap water falls within this range, but always test and acclimate slowly.

- Acclimation: Always drip-acclimate Serpae Tetra over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
