You may have heard: “Fish only grow to the size of their aquarium.” But that’s not true!
Fish have a natural growth potential based on their species. In too-small tanks, they don’t actually “stop” growing — instead, they suffer from:�• Stunted growth (organs keep growing while bodies don’t)�• Shortened lifespan�• Stress and weakened immune systems
Fish need enough room to swim, explore, and thrive. Providing the proper tank size means healthier, happier fish that live to their full potential.
What are some other common aquarium myths you hear?
