Danny, I've used this same epoxy for months, will no ill effects. I would doubt that it's the cause, especially since your more picky corals are doing well.

It's bizarre, though. And unfortunate...those look like nice Yumas!

Is it possible that your water conditions are too good.

If your nitrates are very low your shrooms could shrink down like you described and maybe this could eventually kill them.

The same with the clam which feeds on nitrates.

I stopped tested for NO3 after a couple years of never having any, I don't even have an NO3 test kit right now.

Well, we'll see if thats true because I found my 6 line dead yesterday (killed and partially eaten) so I'm bound to get some nasties in that water from that. If my clam opens up and my shrooms start to grow back I'll let you know.
