what kind of endler/guppies did you get?
oh, I introduced a gorgeous orange flame tailed guppy to my black bar enlder stock a while back, just to see if I could breed something interesting. Long story short, no. The males don't usually have a flame tail, and look like diluted endlers (which they are), while the females have blue tip tail most of the time.
they are, however, one of the only things that survived last summer's cross country move, and are great for surviving and cycling new tanks, so hence...
