Anchor worm? Or something else?
I noticed a couple of my tiger barbs starting to flick themselves on decorations in the tank. I've been keeping a close eye them for the last three days and today I noticed something on the pectoral fins of one of them, they look like white threads. I managed to get a photo and have attached it. Is this an anchor worm?
I've had the barbs for about three weeks now and added two nerite snails a week ago. Could this have come in on the snails or would it take that long to start showing up on the barbs?
At any rate, how do I get rid of whatever it ends up being?
