Alright so i set up a tang tank awhile back with brevis and occys and everything's was going fine, but a couple a days ago i noticed the brevis were starting to get a blackish/brown on the edge of there bottom fins, on one of them it seems to have spread to around its mouth, it hasnt effected the ocs, i have no idea what it is, its not black ick, i thought at first it could be fin rot but its the wrong color, i havent noticed any of them not eating, there fed nls, ph around 8.4, tank params are where they should be, and ive been using lake salt in this tank, i snapped a couple pics but you cant really tell, im gonna keep trying
this is really starting to frustrate me
so any help finding out what this is would be greatly appreciated thanks
