you are not easily going to find a name , thus is a fish that has had parents that were one endler, and one guppy . nice lyretail thow, I have true endlers, and the tail , and the one black spot look endler, BUT the face, and front end look true guppy . so , um you can etheir get more guppys and make a new breed, or get some true endlers and have the breed a new little bit bigger breed,. since endlers only get about 1/2 in adults. well true' endlers, and guppys well the get on up there. LOL but you can do whatever ethier way this is a pretty blue endler/guppy hybrid. good luck .
