What are these fry?

It hadnlt occured to me that gambusia and endlers would hybridise. If they can I should probably move the endlers to my other tank....
 
They're cute tho :)
 
Hybridization is extremely unlikely. Despite their similar appearances, Gambusia and Poecilia are not that closely related within Poeciliidae. Also, they have different chromosome numbers (2n=48 in Gambusia, 46 in guppy/Endler).

Get a better pic but based on the body shape it's most likely a Gambusia.
 
No idea.
