Maybe your entire existence is shrinking at the same rate your fish are growing making it seem like they are not. Seriously though I never have an issue growing fish with a varied diet clean water and unstressed tankmates.
Well i know forsure that bigger tanks make fish bigger.
for small fish, larger tank may lead to slower grow or even dead because they have a difficult time finding food!He's right! Larger aquariums induce faster growth~ Also more dominant fish will eat more (shoving fish out of the way) and intern with grow larger than others. Just some variables you may want to consider.
