I don't know if they would or not, but I keep them in separate tanks, just in case. If the time comes that I'm lucky enough to have them spawn, I want to be sure they are all good ones with no mixed genes in there.
Usually corys prefer to spawn with their own species, but since they haven't yet been completely studied and their classification settled upon, I don't know what the results might be.
I don't know what Magic Isle usually stocks. I don't get up that way very often and it's a treat when I do.
I love the orange lazers I think I will go to my lfs and see if he can order me some. between Inchworms little black cories nad now these , I think I see alot more cories and tanks in the works.
