this is a picture of a friends hippo tang. we have tried all kinds of treatments;rxp, garlic, zoecon, ect. any other ideas will be appreciated. thank you
ph is 8.2, amonia is 0, all others within specs. i was told ph has alot to do with color. the tank mates have all been together for 6 months. condition has slowly worsened from a month ago. he eats and is active swiming around the tank.
