Betta fish much smaller than others
I've heard this theory before. It's interesting b/c it begs the question....why doesn't the hormone circulating in the water also affect itself?
Some says that it does also to a certain extent. this experiment is not hard to repeat. buy 2 baby betta from a breeder, of the same age and size. put each in the same environment. except one gets water changes whilst the other does not.
