Are these from wild or could a cultivated guppy could of got in somewhere?
There looks to be some with top swords in your mix. Just it took hobbiests over 50 years to develop the top sword from the early collection in 1900 until 1950, the big delta tail were then not developed still until around 1960's.
Also lots of yellow i can see, this not to common in wild fish, other wise the fish do look your typical wild fish.
Thanks for replying, and the information, if you wouldn't mind looking here again at post #14 for what I know about them. btw their tails are solid its the colour pattern that makes them look like a sword.
