be careful when using growth hormone, using it too much or too quickly in a tank can cause pregnant fish in the tank to 'abort' pregnancies.

WOW, I did not know that!

I have not had that happen, i have used the growth hormone an awful lot and very, very often, and only times pregnancies did not produce babies was when the tank was already full. Maybe I've been lucky!

I have not experienced this either. Anyone else?

i have used drop after drop in a tank where there were babies and pregnant fish, and none of the fish that were pregnant had babies, so i can only assume it was the growth hormone. i hadnt put anything else in the tank.

it does tell you to be 'careful not to use too much' when you purchase it. i try to heed that warning now!!

I've never tried it in a tank with pregnant fish. I have however taken babies into adulthood in a matter of minutes with 4 drops. You can get a lot of Canary Fire-Arrows that way.

OK, being the curious type that I am, I just had to try this out. I had 6 fish at various stages of pregnancy and put some growth hormone in the tank. Some babies appeared instantly, but not as many as would have been expected.

My guess is that since the growth hormone "jumps" the fish a certain number of days in age, whether or not they produce babies depends on how far they were from giving birth. If they turn the age when they would have given birth, you get instant babies. If they don't quite reach the age when they would have given birth, the babies will come sooner, but you still have to wait. However, if they pass the age when they would have given birth, they are deemed to no longer be pregnant. However, since the birth didn't take place, there are no babies in the tank. Hence, you lose the money for the babies and the money spent on growth hormone.

Are you sure that you don't have to many fish in your tank (Your only allowed 21) and thats why your not seeing babies?

im positive, i always keep 6 pregnant fish in a tank with a greenfin spot (19 total after birth)..i NEVER keep anymore than that so i am sure to never lose babies due to a tank being full. once the babies are born, i move them to the sell tank..when i have a full tank of babies, then i use the hormone

this system has been working well for me. all the babies are in one tank, and i think the hormone is utilized better when all 3 drops are used in one tank, not divided among 3

shoot, for $380, my babies better be grown up after i use a bottle of that stuff!!!

I normally find that 3 drops won't fully grow all of my fish
