i have a question i hope someone can help me with?i have a yellow tang bought 2 weeks ago it seems to be alright most of the time but occasionally looks as though he's trying to get something off him.took a close look seems he has tiny black specks on both sides does anyone know what that might be? cant find any info on that issue.some help would be great.i'll tell you water param: grav:1.024 temp:80 ph: 8.2 i have no nitrates at all use only penguin dual biowheel 2 pro head 3 power heads no skimmer but have had tank set up for 8 months without any water problems use r/o water.
