Well I lost the pictured mono, the disease was too far advanced I suppose before starting my treatment... but my other 2 mono's of this species who were starting to develop the same symptoms have halted and then improved from the medications..
ive been using marcyn 2 + quick cure and melafix... I will update you all again if the disease dissapears entirely.
and as far as my water quality, i havent had a chance to get a test kit lately, but i do regular 25% changes every week, and also run a U/V sterilizer and protein skimmer on my tank.... so.... not sure how this disease happened. I will step up my water changes to 30% from now on in the future and make sure not to slack on it!
