Coral not opening

Hey guys, i have a xenia that is open and pulsing fine. But then i have green star polyps, and i believe they are called zoanthids. The zoanthids and gsp are not opening. Ocasionally one or 2 will slightly open. I have a fluval edge 6 gal. Salinity is at 1.025. I have the reef master test kit and that all checked out at the levels it recommends. The only issue i can see is 2 much current. The filter poors down right ontop of the corals. And i also have a power head that i turned off untill my xenia sticks to something because it was getting blown around 2 much. Any ideas? Should i try moving the coral off the live rock down to the substrate so it will be away from the filter current? The filter does around 100gph.

hey i got the same thing happening with mine. i have two polyps one is completely open and the other closed up today but saturday it was closed from the move from the store and open in less than an hour after its intro time. i know its not the light cause im using a 14k coral growth light and a blue actinic light so what else could be doing this??? also will hermit crab hurt the corals? ive seen some walking on the corals and was wondering if they would do any damage.

thanks for any help

Depends on what kind of hermit crabs. But, just by walking over them, no, they will not hurt them doing that. 2 Polyps? As in Zoo's? Or Palys? If you have one open, its only a matter of time before the other responds. But, there is always the case where one acclimates and the other does not. I would not mess with it though, just let it be for the time being.

i would let it be for the time being as well. whats the flow like in the tank? also if it is zoanthids it can be a number of things, like zoa eating nudibranches, zoa spiders, zoa pox, certain fish picking at them, and im sure other things.

a 14k light and an actinic only tells me your tank appears alittle "more blue," im going to asume these are t5s? and its just the 2 bulbs?

there t5 dual lighting system. and there zoanthids. the water flow is low right now( about 200gph) because i took the power head to the new tank which will be complete in the next week. i also have a colt coral which seems to be healthy. i havn't feed them yet this week it could be that but ive only had the corals for only 3 days now.
