Anyone know or have experience of Heterandria formosa x Poecilia reticulata hybrids? I found a guppy look alike fry in my tank. I havent had guppies in that tank over 7 months and have not kept guppies in 5 months. I recieved some least killifish from the auction but this little fry I pulled out does not swim like a least killifish and looks like a guppy fry with least killifish dorsal and ventral fin. Anyone know if least killi x guppies possible?
