Not sure if this is a major problem or not, but I've had a large hammer coral in my tank since I started (about 8 months now) and its always been out flowing & billowing with the flow of the water in the tank.
Just recently tho I've noticed that some parts of the coral are not coming out the full way (or at all). the majority is still out every day, there are spots that arent.
When I purchased it from the LFS, they said that it was a faairly easy to look after coral without many demands except water flow & good water conditions.
The flow in the tank is good, the coral is getting ample light (no MHs or T5s though) and the water conditions are testing fine (ammonia, ites, ates are all minimal if not zero, pH is fine as is salinity)
I feed the inhabitants of the tank with mysis shrimp regualrly so Im hoping that if the coral needs to feed it may pick up the odd bit from the mysis shrimps.... or not (?)

Any thoughts? :idea:?

i use coral gro by red sea , and have you tested calcuim? magnes? can you tell us more about your lights?
 
Hammer corals really need a minimum of T5's to thrive. Anything under that and it will just about survive but will never flourish.
What are your phosphate, magnesium, alkalinity and calcium reading?

As long as you have the proper wattage all Euphylla should do fine under PC's, even flourish. Lux isn't a huge factor with these corals.

Wattage means nothing par is whats important in lighting and yes they should be under at least T-5's IMO, if you have them under PC's they should be up high, keep your calcium, alk and mag at the proper levels and good lighting and they should do fine. When you got it how many heads did it have and how many are there now, it might be splitting heads
 
my branching hammer did this recently .. a low pressure system had hit and they retracted. I also found that a torch coral has sprouted on one of the branches off one of my hammers.
