Not-so-old Sea Dog
I have a very healthy hippo tang about 1.5" with no signs of HLLE or any illness. Last night I turned the lights on about 30 minutes after they had been out and when he came out of his sleeping place his black stripe was completely clear. I could see through the fish and see it's brain. It colored back up in a couple of minutes but could somebody explain what happened and why this happens?
