Hi everyone~ I am new to the fish community and have a few questions for you all.... My son got a guppy from the store a few days ago. It was huge compared to the other guppy in the tank. So we assumed it was preggo. It's gravid spot was black. Last night my son told me that the spot had turned bright orange with black speckles. I wouldn't have believed him had I not seen it. It was bright orange and indeed had black spots in it. We moved her into a breeder net and now it has changed back to black again. Is this due to stress that she is changing colors? I don't want to hurt the poor fishy. We read that they need to be seperated if they are pregnant. Any help would be appreciated. Thanks in advance.
