Well just like any coral, it can look perfect for weeks then all of a sudden look terrible. My hammer hasbeen in my tank for 3 weeks and has looked amazing. All of a sudden it's all deflated and it's been this way for 2-3 days. Here are some pictures.
Here it is now..
I did a 35% water change yesterday. I only have 1 fish in my nuvo 20 with 3 other zoas. Temperature and salinity don't swing. What could be causing this??
