I've had this Midas Blenny for roughly a month now, but I just noticed the last three days he hasn't really swam. Just stays in his little cave underneath the Zoas until it's time to eat, and he may swim around for a few and grab some food but then he immediately spits it back out. I haven't seen him eat in at least 3 days.
During this span, I really noticed a spot under his right fin. Can't make out exactly what it is, nor can I seem to get any good pictures.. I'll post the few that MAY have some lead or help with identifying whatever may be happening.
Any and all help is greatly appreciated!
