What to Feed Your Tetras?
Tetras take any food thrown their way without fuss. Their omnivorous diet means they get along well with high-quality flake or micro-pellet food supplemented with occasional frozen foods such as brine shrimp and daphnia and bloodworms. Tetras should receive their food once or twice daily but owners must watch carefully for conditions that lead to overfeeding. A practical feeding guideline? Feed them only what fits into a two-minute feeding window.
Proper nutrition maintains their immunological defense system, creates better colors, and produces better breeding results for a small group of baby tetras.
