Hi! So out of the 15 or so guppy fry I found a few weeks ago, I have only one left.. T-T However, I have noticed that the fry has gotten bigger and hadn’t been chased by anybody else in the tank. I was wondering, since the guppy in the tank is female, around what age can you tell the gender of the fry or it’s type/strain of guppy if at all? I have noticed some black coloration from the base of the tail up the sides of the fry. I will post pictures with the fry circled. Thanks!
