urchin with infection

[salty joe]

My tuxedo urchin which I've had for over a year suddenly stopped hauling bits and pieces last night. Today, I see a greyish white patch on him. It's still alive. About the only thing that I think might work that I have is hydrogen peroxide. I want to swab the infection. Should I dilute the peroxide? It's the generic stuff, 3%, I think.


Tank parameters seem to be not way out of line alk 8.2, mag 1140, Ca 360, salinity 35ppt temp 79

Let’s see if the squad can help.
Hope he gets better

Thanks, but it's dead. The stuff on it was rot, I think. He stunk. He went fast. I saw my sandsifting starfish today and it looked good.
