Well we have had him a week now.
As for how he' s acting, nothing seams out of the ordinary (this is my first marine fish so i don't have anything to go by).
However he appears to be just doing his fish thing, no scratching, not lethargic.. he eats like a horse when i feed him (once ever 2 days) otherwise calmly cruising around the tank.
No visible sloughing
It doesn't appear to be dots.. I think the best way to describe it would be mildew like.. just a slow progression of the black discoloration.
The tank itself has remained stable for the past 2 1/2 months, Amonia, nitrites have stayed at 0, Nitrates havent gone above .5 since week 2 and usually stay at 0. Temp sits constant at 79-80 and salinity 1.025. and weekly waterchanges
There is nothing else in the tank other than liverock, 2 hermits, 1 nerite and a bumblebee snail and a peppermint shrimp.
