Most of my reef is looking fine..... But my torch and frogspawn are no longer putting forth their polyps like they did when purchased and slightly thereafter..... They both have been in the tank over 6 months...... They are both located near the bottom of the tank..... There are no other corals within stinging range....... One head of the torch died off completely and was removed....... the polyps on the torch now extend barely 1/4 inch out of the skeleton........ They had been as long as 1 1/4 to 1 1/2 inches long ago........ The frogspawn is very similar...... About 2 months ago, (while away from home for 1 week) my tank was without power for 4-5 days, but the problem existed prior to this....... Most everything survived and has since recovered, except for these two corals....... Any suggestions / comments ????
 
Are they close to each other? The torch is the only euphyllia species that needs to be away from other euphyllias. They can't live near frogspawns or hammers.
 
I haven't noticed anything irritating them........ I only have a small Fairy wrasse and a purple firefish in the tank....... They are not in the sandbed, their bases are wedged in rock, but their heads are upright and near level....... The perplexing thing is that another recently added (3 weeks) torch that is also wedged in rock nearby is doing amazingly well..........

Too much light perhaps? Looks like you have 2x400watt bulbs over a 125g. Just a thought...

I would guess that it is a negative reaction to a change(possibly a much higher par bulb/clean reflector combo) in lighting. If not lighting, flow.
