Gramma loreto
Quick reference

Length matters more than gallons for active swimmers.

8.1–8.4
Feeding
Small carnivore. Mysis, pellets, brine shrimp. 1–2 feedings daily.

Common mistakes
- •Buying two — they will fight unless the tank is very large with multiple caves.
- •Mixing with chalk bass or basslets that look similar.
Equipment & food for this species
