Fish hybrids

Not plant related, but found these old pictures from when I was playing around with interspecies fish crosses (back 15 or 20 years ago). These hybrids came from virgin guppy females kept with various molly males. The three stripey looking ones on the left were from sailfin type molly. The other three are from a Gold-Dust Molly. All F1 offspring were male and I never got any further generations - I think they were relatively sterile - but you never know. So I thought maybe these pictures would inspire someone to give it a try.
