Hello all, I recently bought an A+ grade BLUE moscow guppy and the shop I bought it from gave me this BLACK male moscow guppy as a free present. Now I am not sure if I just got it for free because the guppy is crooked. His body from head to tail is not strait but more a boomerang shape, or a C-shape His respiration is also very fast, faster than other guppies. The video: In the meantime this (crooked) black male moscow guppy has exclusive bred with a black female moscow guppy and together they have 2 batches over 30 fry. The female guppy mother is in excellent shape and I am even thinking of using her to crossbreed with my blue moscow guppy line. My questions: 1) how long does it take before the sperm from the black male moscow guppy is out of the system of the black female moscow guppy. 2) if it were to take too long and I introduced a blue male moscow guppy today, would the next batch, or the batch after already have some mixed blue/black guppies ? 3) what to do with the 30 fry that I already have from the black male and female moscow guppy if the black male really is crooked? Sure even the young females would not be good to breed with any other blue guppies because they will have the crooked characteristic in their dna from their father correct? Those are my questions for now. Thanks in advance!!
