Do fish grow in relation to the size of the tank?

This is a common myth and is not true. Some fish will have their growth stunted by being kept in smaller tanks, which can lead to growth deformities.

However, most fish will simply outgrow their aquarium in a heightened level of stress, often resulting in decreased life expectancy and/or leaving the owner with the difficult task of re-homing their large fish. Common fish that this happens with include:

✔  Plecs
✔  Clown loaches
✔  Angel fish
✔  Oscars
✔  Red tail catfish
