I noticed tonight that my Kole Tang (had him since 20 AUG 2011) was more laid back, stayed within the rocks and definitely not aggressive (towards food not other fish) when it came to dinner time. Normally he would be the first one to grab at the food but tonight he didnt eat at all. "Bubba" seems to be breathing a little heavy and his mouth constantly stays open. The other fish (including my yellow tang), shrimp, and crabs all are acting normal and seem to be as happy as can be I will say my salinity is to high (1.035) so I have been slowly adding RODI w/ Prime (as an extra precaution). Thoughts? Oh I do run an air pump in my sump if that makes a difference.
