I've tried getting a picture of the spots, but the blue tang is moving too fast to get a decent picture. They are all blurry. They have all been in hypo now for 8 weeks and I am still seeing these whiteish bumps that look like they are slightly under the skin of my blue tang. I have also noticed some white cottony spots on one of my percula clowns who is also in hypo. I'm afraid to leave them any longer in hypo because of the possibility of kidney damage. And whatever it is, the hypo obviously has no effect on it. The spots don't seem to be affecting them. They all eat great and don't scratch on objects. Otherwise appear healthy.
The other thing is that my yellow tang (also in treatment) has retreated to the side of the tank, has stopped eating, and all of his fins are frayed at the ends. I don't see any signs of spots on him though. He is getting very thin now.
For since the creation of the world God's invisible qualities...have been clearly seen, being understood from what has been made, so that men are without excuse. (Romans 1:20)
