Guppys tail split

[connorlindeman33 33]

So i removed the one fancy guppie from the 10g to the 20g community tank(neons, red eye tetras, cherry barbs, and two corys) so that i could add the new clown killis. Just now i notcied that the guppies tail is split down the middle. Hes staying near the heater by himself. What should I do?
