I got this coral from someone who was going to throw it out and does not know what it is and what’s wrong and I would really love to save the little guy, any help would be much appreciated I can’t find any pictures of this coral anywhere and what it should look like and what’s wrong with it.
This is too smooth to be a hammer and is a duncan. It is almost fully receded and may or may not come back. It will require proper alk and CA and salinity to have a chance
It's hard to say whether it will make it or not! I have a Duncan in my tank that has closed and opened many times over the past two years. Multiple times I have thought I was going to lose it (even lost a head at one time), and if it was not glued to my rockscape I would have taken it out and dipped it. With that said, I didn't dip it and it was able to make it on its own and is now thriving again. I would probably let it settle for some time longer since 2 hours is a very short time! That is my opinion, hope it helped!
