I recently bought a male guppy to replace one that died in my daughter's little tank. I also grabbed a female (they only had two and this one was more colorful on the tail...) I have these two together for now but will put the male with the other two males in my daughters tank. As I watched him swim around I started thinking he had a lot of endler characteristics. They often have endlers (assuming hybrids) and also of course guppies. I do see some hybrids from time to time. I didn't intend on getting a hybrid but this guy sure is pretty whether he is or not. Does he look like one? I see the markings on the sides and he is very small, I cannot be certain if that is because he is young or if he is a hybrid. I'm just curious!
