Have had issues in the past with HITH with other fish, but never anything like this. 4 days ago I noticed a small pimple or scab on my Midas. Now today looks like a single large hole! He has no other marks on him except this hole. Weekly 30% water changes. 0/0/10 water. Fish is 7 years old or so and never any health problems. 150G tank shared with Melanurus and a few plecos. Fish is eating and acting normally.
Any advice or suggestions?
