My scopas tang and blue hippo have always been very good well behaved tank mates but lately it has gotten a bit extreme and I'm worried that my hippo tang may be sick. They follow eachother around all day and the scopas tang will allow the hippo tang to lean against him. The only way to describe it is like when two people first fall in love. Whats worrying me is the the scopas tang is very gently cleaning the hippo tang which leads me to believe that there may be some kind of parasite that he is trying to get off. They are both eating very very well and I feed them sea weed (three times a week), pellets daily, and they both eat when i put meaty foods in for the other tank mates and when I add amphipods and copepods they will pick a few off here and there. Does anyone have any suggestions ? or should i just be glad that my scopas isn't a jerk
