I have a hammer coral thats not doing good. He has left his skeleton. And keeps decreasing. I fixed the light and flow. Nothing was touching him also. Just did a water change and fhe Peramiters seem to be in check. I did not see any vertimes snails. I dont know if this has to do with my hammers.. But my hand got bitten up immediately as soo as i rised off my aquitment..any ideas what is going on..
