Guppy fry mortality in the first week can reach 50% even in clean water. The cause isn't disease—it's treating the tank like a miniature adult tank instead of a neonatal incubator! In this video, we explore why fry need strict environmental control, how strong filters and temperature swings cause fatal shock, and why keeping adults away is vital. What you will learn:The Neonatal Logic: Why fry need incubator-level precision to survive their fragile first weeks. The Filter Trap: How regular filters suck fry in and why a sponge filter is mandatory. The Mother's Instinct: Why adult fish—including the mother—prey on fry naturally and how isolation prevents sudden disappearances.
