Know when fry become free-swimming
Some larvae remain attached to a surface or absorb a yolk sac before feeding. Starting too early fouls water; starting too late loses growth and survival.
Match food to mouth size
Infusoria-sized foods, powdered prepared diets, microworms and newly hatched brine shrimp suit different species and stages.
Feed small amounts and observe
Frequent tiny meals can support growth, but uneaten food can quickly overwhelm a small system.
Expand space as biomass increases
A tank that is adequate for a spawn may become crowded within weeks. Plan transfers before growth stalls.
Keep records
Dates, foods, water tests, losses and growth notes help identify what worked without relying on memory.
