I would like to think a little common sense would prevail and obervation of ones fish, I would like to consider myself able to judge if a fish has become too big for its aquarium - though so far I have not had this problem.mrV said:If they do get too big after a few years then its time to get a bigger tank!
How do you know, when its time to move fish into bigger tank? They grow slowly, but you must remember, that aquarium size affects growth of fish and especially when fish are young, water values and aquarium size is important.
So are you saying no-one would be able to tell when a fish has outgrown its tank?
