🔵

Quality flake or pellet food Twice daily, only what fish consume in 2 – 3 minutes; species-specific pellets beat generic flake

🧊

Frozen food Brine shrimp, daphnia, mysis shrimp — 2 – 3x per week; thaw in tank water first

🐛

Freeze-dried food Bloodworm, tubifex — convenient supplement but nutrients reduced by drying; don't rely on it heavily

🥦

Blanched vegetables Zucchini, cucumber, peas (shelled) — essential for herbivores like plecos and livebearers

🌿

Algae wafers / sinking tabs Daily for bottom feeders — cories, plecos, loaches won't compete at the surface; feed at lights-out

⚠️ Overfeeding is the #1 water quality killer — uneaten food rots and spikes ammonia. If food hits the bottom and sits, you're overfeeding ⏸️ Fasting 1 day per week is fine and beneficial for digestion 🦐 Live food (daphnia, baby brine shrimp): occasional enrichment treat only — quarantine first, as live food can carry parasites 🐠 Community tanks have mixed needs — livebearers are largely herbivores, tetras more carnivorous; alternate protein and plant-based feedings
