Yesterday morning i fed my spade and humu trigger and everything was fine. Noticed that they were rubbing on a peice of rock a few times but didnt look like anything major. That night, I looked in the tank before i went to bed and the spade was COVERED in white dots that looked like sugar. I said "oh no" and went to bed. woke up today, most of the spots are gone. should i pull him out and put him into my 20gal long and put my small snapper into the 55gal and treat him? what are my options. cant do copper in the main tank because i have too many inverts like starfish and crabs and snails. going to my lfs
today and see what they think would be the best course of action.
