Trumpet and Branching Hammer Help

[is350jonny]

wanted to see if anyone can give me some insight. so ive had these 2 corals for about 6-8 months already. Started off with 5 heads on the trumpet coral and 4 heads on the branching hammer. They keep splitting heads but would never fully inflate.

Everything else in the tank from birdsnest, catspaw, xenia, gsp are thriving and growing like crazy.. just for some reason these 2 branching types wont fully open.

also, my anchor hammer is doing well, but is losing its florescent green color. before it was super green.. now its just purple.

LPS corals like lower flow areas. They will split and seem happy in other ways but in a higher area they won't fully open in fear of being damaged. If the flow is indeed low... I really do not know what it could be. Sorry.

Put the hammers on the sand bed in med-low flow areas as for the trumpet\candy cane I have no idea mine don't fully swell either....
