Given the size next to the penny it's not that big. If it were me I'd just throw it back in, but if you killed it no big deal also. Where there is one there are many.

Good part of cuc. (Clean up crew). If they concern you can always make a trap and remove them that way.

I've had them in my tanks up to 6" long. They're ugly, but beneficial. I'll pull them outta my 'fuge and put them in the display to help the CUC.
