My mate has 15 1 month old guppies and I noticed today that one of them has a deformed tail. It swims realy well and is quite healthy. The tail is realy long but it doesnt have any shape, its just a whip kind of thing. whip tailed guppies would be quite cool. If it survives im going to help breed some more. look out for whip tailed guppies in the near future and you will know who they came from!!! Does anyone else have anything like this?
