Hi,
What is the best way to visually mark males and females? I have seen some breeders use what looks to be paint of some kind. They put a pink dot on the back end of the females and blue dot on the back end of the males. For now I only have them separated because I don't want to mix the sexed ones up with each other as I will never be able to tell them apart.
What product or paint would be safe to use for this?
It will have to be waterproof as well.
Thanks Steve
