Need to rehome:Pleco

My sister doesn't know about the cycling process. I am no where near to finish my tank cycling. She just bought me this pleco the size of an aldult-thumb size from Petco for $15. I don't know the ht specific of this pleco, but my sister told me that the saleman said this pleco is special type to live in planted tank without destroy planting and aquascape structure. I can't take picture but the pleco has stripe like this (not exactly sure since I am no expert):
I would like a $10 rehome fee. Please help. Can't return.
