I just noticed this on my Xenias… I don’t know what it is and it started at the yellowish spot on the s.. and now that head it completely gone. It’s spreading cause I started seeing the same things on my other stalks of Xenias(but none of the other corals) and I have no idea what’s going on. All my parameters are normal except for the ammonia which might be at .5ppm due to the loss of a Kole Tang (I haven’t seen him in a few days and I cant really get to behind the rocks.. to get that waste out)
Please advice on what I can do.. I’ve never had to deal with any Coral diseases and I don’t even know what this is!! Should I take out the xenias to try to save the other corals? I’m doing a 1/3 water change tonight… Hopefully it’ll help a bit.
