Feeding Your Rummy Nose Tetras
Feeding these fish is simple. Variety of food is also essential for health and color enhancement.
Diet Breakdown
- Staple food: High-quality micro pellets or tropical flakes

Daily two to three times meal is ok for tetra. Always avoid overeating. Extra food goes to waste and spoils water quickly.
Tank Mates: Who Gets Along with Rummy Nose Tetras?
Rummy nose tetras are gentle, non-aggressive, and perfect for peaceful community aquariums. But who should you pair them with?
Great Companions Include:

Breeding Rummy Nose Tetras
The Breeding of tetra in captivity is challenging, but definitely possible with the right setup.
Breeding Conditions:

- Diet: Condition pairs with live or frozen food
