How big is it? If it's small it shouldn't do any harm. If it's small and you don't want it, get a peppermint shrimp if you want one or two (I've got three and no longer any problems with aips).
If it's larger and it really bugs you, get some Joe's Juice. The stuff works great and it comes with a syringe to squirt it. You can get two shrimp for the price of the juice but mine haven't tackled any aips that were too big.
