Is this normal for a hammer coral??

[gaetyn]

Hello,
I have a question about my Green Wall Hammer's behavior the past few months. During the day my hammer has very long and thin pollyps. It kind of looks like sweeper tentacles. Is this normal? At night it closes up and "goes to Sleep" like the rest of my corals. My params are:
tank sixe 55 g
temp 81
specif gravity 1.26
nitrates 0
nitrites 0
lighting 4xt5ho (3 ati blue plus 1 ati coral plus)
calcium 420
phosphate .25 via api test set. this is high but i recently started runing gfo to help lower it.
tanks been up and runing for almost 2 years
I do a weekly waterchange of 6 gallons with ro water using kent reef salt
My other corals and inverts are doing fine. Any input would be great

Those are sweepers, it's trying to kill everything nearby. I have a wall frogspawn that will try to kill everything, including branching frogspawn (I lost 3 heads before I realized what was happening). The wall varieties seem to live by their own set of rules.

+ 1 . Sweeping,
Have you added any new corals ?

I havent put anthing recently but i have a fairly large coly of mushroom coral that have seemed to relocate themselvs into other parts of the tank. There is a small one that is about 3 inches away.
