I have a neon green palau nepthea frag that i bought the other day. This frag did great yesterday and all day today till about 3pm when i noticed it seemed to be not able to support its own weight and would bend over and just lay on the rock. when i saw this i did a extensive water test and all my levels were great. I do not know weather this is normal or if this is cause for concern can anybody please elighten me.
