wow the female is amazing!! my babies are taking for ever to get big, yours seem to be growing quicker and im feeding brine shrimp to. funny some of mine are now the size of guppies but some still are about the same as week 2... any of yours like that?
This is from a book that I have called The Betta Handbook by Robert J Goldstein, Ph.D.
'The best growth doesn't result from heavy or frequent feeding or even the most nutritious foods, although they all help. Optimal growth (fast and even) is attained by frequent, massive water changes that remove the growth- inhibiting nitrogenous wastes of the fishes themselves. '
I hope this helps.
