Feeding and the health watchlist
Micro-pellets, crushed flake, frozen bloodworms and brine shrimp — small mouths, small portions, twice daily. Watch for: ich (white spots — raise to treatment temperature per product directions), neon tetra disease (fading color patch, asymmetric swimming — incurable; remove affected fish), fin nipping (usually a sign the school is too small or the tank too empty), and wasting in old wild-caught stock. Quarantine new fish 3–4 weeks; it prevents most heartbreak.
Choosing species honestly
Beginner-safe: neons, cardinals, embers, black skirts, bloodfins, glowlights — all peaceful and forgiving. Special-case: rummy-nose (excellent water-quality indicator, sensitive), Congo tetras (bigger, 90 cm+ tank), serpae tetras (fin-nippers in small groups — 10+ calms them), bucktoothed tetras (not community fish — aggressive carnivores; avoid). Cardinais vs neons: cardinals are more colorful and slightly hardier but cost more and prefer warmer water.
