I would say leave it and let it regrow. My marble pims wiskers have gotten broken/bent a couple of times by tankmates and it grows back either falls off at the bent part or heals itself.
Hey Xcuter. I dont know what will happen if you leave it alone. But if i were you i would cut it off. I had the same problem with the tig i bought from you. It broke very close to the root and I cut leaving 1 inch but it still grew back perfectly. At first it will grow back looking little curved but will straighten as grows. Took 2 months i think to fully regrow. GL
