Hi everybody.

My name is Rui and im from Portugal.

I would like to know what does the unknown chemical do, as ive used it in pregnant fish, small fish, big fish, ... mainly all kind of things and it has done nothing...

Is it normal?

Thanks in advance.

Hi! There have been several pretty good discussions about that chemical. This thread will tell you a little bit about the Unknown Chemical and also give you help with finding the other discussions!

Thanks for your help.

will unknown chemicals change pregnent fish? if yes, what will happen to the baby? would it change too?
