Hi all. I am new to saltwater bought a used 30 gallon bow front from a guy. has several corals I need help identifying so I know what kind of care they require. I have done a fair bit of research about saltwater and figured I might as well take the plunge. I have attached photos of all the corals if you guys can help me identify them and figure if they in the correct spot in the tank or not. The guy told me for sure that I have to target feed the orange one with tentacles (Sun coral?). are there any others in here that require that? also I have two wrasses in the tank which have buried themselves since I set the tank up. How long do they normally stay under the sand? any help or advice is much appreciated!
