Feeding a Molly: omnivore diet, frequency, mistakes
Molly : Strongly vegetarian: spirulina and blanched vegetables should dominate, supplemented with flakes and occasional frozen foods. A lack of plant matter weakens its digestive system.

In short: 6 to 10 cm as an adult, 100 L minimum for a group, hard water between 24 and 28 °C. Active, sociable and a keen grazer, it enlivens the surface and decor all day in a female-dominant group. It needs warm, hard, alkaline water: in soft acidic water it quickly develops the shimmying disease.
Feeding a Molly: diet and habits
The Molly is an omnivore: a quality staple (flakes or granules) varied with frozen foods and greens. Its table is in midwater: offer slow-sinking food, dosed to vanish within two minutes — the surplus only feeds nitrates.
Frequency and variety
Feed little and often — one or two small servings a day — and grant a weekly fast without guilt: excess, never shortage, is what ruins tanks. In a group of 5 or more, check everyone reaches the food: dominants serve themselves first. Alternate dry, frozen and rinsed thawed prey across the week.
The costly mistakes
The Molly “begging” at the glass is not starving — it has simply learnt your silhouette: hold the two-minute line. Avoid discount flakes that fall apart on contact with water: a serious brand costs only a few euros more per year. The rest of the profile is on the full Molly profile.

Tangs, dwarf angelfish, grazing blennies: these reef herbivores need algae every day, not just carnivore-formulated pellets.
- Overfeeding your fish: the most common (and most dangerous) mistake
Overfeeding fish pollutes the water faster than any other mistake: uneaten food after 2-3 minutes, rising ammonia, algae and disease in a chain reaction.

Overfeeding is usually framed as a water-quality problem. A study on zebrafish shows it also carries a direct cost to the fish's own learning and memory abilities.

No "anti-stress" water conditioner has been validated on aquarium fish. Dietary tryptophan, by contrast, lowered cortisol in several studies — with clear limits.
