This little part of my zoa is not opening, and is whiter than the other parts... Some parts don't close at night, and some don't open at days...
I reduced my light from 75% to 50%, everything look bleaching in my tank except my frogspawn... I turned the zoa frag, so the healthy parts are more near from the light, and the no healty part is under, so it recieve less light, but I don't know what this will do, I'm new to this hobby, and It cost me 25$ for that frag.
I know it's no a beautifull frag, but I wish the rock will be covered
