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!!!
