What is wrong with my Hammerhead coral

[jojo10]

My hammerhead coral is becoming stringy, i think could be because is too close from my mushrooms, is this possible? What can i do to fix it?

May be to get rid of the Mushrooms, and maybe hungry.

Looks like sweepers to me.LPS have some that are hellacious.Move your shrooms or they stand the chance of dying

sweepers its trying to kill the corals around it so it has more territory

Thank you all for your comments!
Reefing Madness, thank you for the link! I just learned something new - really fascinating!
I saw these tentacles stuck to the mushroom a couple of times and since then, I see more "sweepers"...
I just fed them Dr. G's phytoplankton, hoping is about food and not much about space (wishful thinking). I have a 29 Gal. Tank and not too mush space available. If the hammerhead wins the battle is not so bad. I can't move the mushrooms, they are on a main rock and spreading like crazy. I just hope the hammerhead wins [emoji26]

sweepers making space for itself to grow... move the mushrooms
