I'm new to this, but against peoples advice, i put a mushroom polyp (a frag from my LFS
) in my newly cycled tank. And its doing amazing. I'm feeding it micro plankton as its a new tank and obviously without all the nutrients needed, but after having seen polyps developing on my live rock (i belive they are button poylps or sea mats) I thought i'd take a chance. There are loads of different varietys to choose from.
