Both of my rainbows have developed little white dots on their eyes. it kind of looks like ick but is only on the eye. It happened shortly after I added a ton of new mopani wood that has now turned my water black (don't know if that's significant). Any ideas on the ailment and treatment?
P.S.
can't use copper sulphate because I have inverts and live plants.
