Questions - Need some input

I was looking at melevs reef and look at LPS and found a Octopus coral. Do I have a octopus coral? see my profile pic was ( I thought ) a frogspawn but not sure what it is. It was sold to me as a frogspawn for $49 but is it worth more? are they rarer too find? thanks



P.S it was almost dead but turned around and is slowly recovering


this is not what it looks like now. only 2 sections of it is ...

is it okey to glue coral to magnets or snails?? If I glued GSP to a magnets and I kept the magnets moving and not let it sit days on end could the GSP still encrust to the glass???
