All my hippo tang has been stressed and has shown small dots of white all over his body the size of a grain of salt . I've been watching and havnt done anything because it seemed to go away. I just started seeing my skunk cleaner all over the tang(hippo). The spots and skin discoloration seemed to clear up nicely but I came home and tonight one if his eyes seems swollen and looks as if Its protruding from it's socket! Is this a n advanced sign of ich, what is it, anyone seen it? What should I do ?
