[billdogg]

As the title says - All other corals are doing quite well, including a torch and a hammer that sit nearby, but I've lost two of three heads on my frogspawn - they just sort of melt away. No other corals have been affected in any way that I can see.

Any and all help appreciated!

It's about 6 months old in my system. All other corals are thriving, water tests as close to perfect as can be expected (see parameters above). I doubt it's water quality. If it were, the SPS would be having issues as well. I spoke to Aaron and Chris at Phishybusiness about it yesterday. I moved it away from the torch, and will be keeping an eye on my Flame Angel.

Is it getting too much light? I have read various posts that some like very little light..

How is coral doing now?

Does it have Brown Jelly? Do a quick google search.

I doubt its to much light with the Sols at 40%
