It looks as if I have two different types in my tank now. I'm not sure if they are the same? Any help would be appreciated. Photo is shot with just a gel filter under ai prime 16.
I don’t think they can change into a different type but I know that different lighting can cause bta colors to change. I’m not a pro but they do look like different nems. They could be the same. I think the black widow would have a purple foot and rose would have a white foot. I’m guessing that you didn’t add a different nem?
