View Full Version : stunted growth?

my parent guppies spawned about a year ago, and their size doesnt seem as large as it should be, except for a couple of females that are okay sizewise. please answer, because i plan to breed platys in the future.

Do the male and female look smaller? Or the fry? Your tank is small enough that the phermones to keep other guppies from spawning is strong, inhibiting them. That, perhaps is slowing their growth.

What is the filtration and tank maintenance schedule? Some fish release hormones that inhibit growth. If you aren't changing enough water weekly that could well be the issue.

I generally change my water every other week, but i might know the answer. Maybe I kept them in my net breeder too long

you should do your water changes every week and at least 25% is best..

What is your filtration?
