Hey guys. Today, I noticed some odd-looking stuff growing out of the edge of the mouth and the bottom part of the eye socket of a bichir of mine. It looks like some white debris but it fans out into thread-like structures. What cures should I use to cure its condition? Thanks in advance.
Here are some pics of its condition (note the thread-like structures emerging from the edge of its jaw):
