I have a small RR Wolverine frag I tipped from my parent colony a few months back. It's slowly encrusting. What I like about this coral is it's super hardy and bright yellow with blue new growth. I put the parent colony in my new tank that had aluminum leaching at toxic levels. My acans, birds nests, lobo, and stylo stn/rtn. The Wolverine frag actually continued to grow. It's super slow grower but very nice. Asking $15 for this nubbin or trade for a montipora. Green digita or even setosa would be great.
