fresh. im sure it hitch hiked on driftwood from the pond

Bad idea,
putting things from a pond into ur tank without sanitizing is just asking for trouble. If u must get decor or anything from a pond i would suggest boiling it before putting it in ur tank next time to sanitize it.

Iv sanitized rocks for my tanks from local rivers and tree bark from a forest for my tarantulas and every thing worked out great

It's probably a detrivore if you only see it clinging to the driftwood. Of course, pay close attention to your fishes' behavior to watch for any scratching or erratic swimming- I'm not 100% positive that species in the photo is non-parasitic. I have not heard of any exclusively-parasitic freshwater isopods; as a group, there are many hundreds of species, and the vast majority of them are decomposers that eat decaying plant and wood matter. The parasitic ones are saltwater, and have a very unusual head shape. (the head is like a shield.) They also consistently fixate themselves to the host fish' gills, or near its eyes. They especially like the taste of Caribbean creole fish and large angelfishes. They will also bite divers. I don't think you have anything to worry about in your tank, but stay vigilant just in case. If they end up becoming a bother to your fishes, a diluted copper-based medication should get rid of them. Remember not to use copper around knifefishes, freshwater "eels," loaches, and other "scaleless" freshwater fishes.

Does it crawl/move around on its side? Looks like an amphipod to me.
