Are pregnant fish immune to the unknown chemical? I THINK that it did change my greenfin carp to a razorback carp once when the greenfin carp was pregnant. So what will happen to the poor offspring? Will it be like the greenfin or razorback?

I belive ther are NOT immune, and if changes are made, I belive the offspring are lost. Poor little things.

I don't think they are. When they are changed, they are STILL PREGNANT! But I can't remember what the offspring was...

I did a test. I had 7 canary fire arrows in a tank, all pregnant by other canary fire arrows. I added one dose of the unknown chemical.

2 of the fish became canary fruitfish. All were still pregnant.

All had canary fire arrow offspring.
