wouldnt worry about the mooning so much as it isnt severe
the other one has 7 stripes like a kigoma (a seven stripe variety)
I have seen Burundi on occasion with and extra stripe
as far as mooning goes I have seen my F1 aplha and F0 females throw an occasional fry with mooning, so Im not totally convinced about inbreeding etc
many times the stripes will darken as they age (not in very severe cases obviously)
either way
if they are male and female I wouldnt suggest breeding them
both nice looking fish by the way
