A Regra

Alimente o que comem em 2-3 minutos. Comida restante = amônia = morte. 1-2× por dia. Um dia de jejum semanal é benéfico. Superalimentar é MUITO mais perigoso que subir.

Por Tipo

Tropicais (neons, guppies): flocos 2×/dia. Ciclídeos: grânulos 1-2×. Kinguios: flocos 1-2× (muito propensos a problemas digestivos). Coridoras: pastilhas 1×/dia ao apagar a luz.

⚡ CalcWolf Insight

Overfeeding is the #1 killer in home aquariums — more than disease or equipment failure. Uneaten food decomposes into ammonia, poisoning the tank. Most fish need far less food than owners provide.
