+1 to this. But I want to take second and focus on the "Stunting".
So apparently some fish (maybe all fish?) produce a hormone that is released into the water that can slow growth.
Smaller tanks = less water volume (obviously) so it's much easier for these hormones to build up and affect growth.
So while it may actually be the case that this stunting can limit a fishes growth, thereby satisfying the myth that a fish only grows to its tank, its important to understand that this is not a good thing to do to your fish.
So if you was to do water change on a weekly basis that will remove the hormone from water??
