📏Hechos sobre Crecimiento y Tamaño

Research Adult Size

That cute 2-inch fish at the store may grow to 12 inches. Always look up the species first.

Tank Size Myth

Fish do NOT "grow to the size of their tank." Stunting causes organ damage and early death.

Growth Rate Varies

Warm water, quality food, and clean conditions accelerate growth. Cold or dirty tanks slow it.

Schooling Fish

Many small species need groups of 6+. Plan tank size for the entire school, not one fish.
