Good News, Bad News

A quick diary update. First the casualties. After a seemingly good start the Medusa Worm has sadly been getting smaller and smaller over the last few weeks and has now vanished from the system. I was going to fish it out into the sump and it might reappear yet but I fear the worst. I do have to say this is probably my last foray into that side of the invert world. Maybe these things should be left in the wild. The hearth Urchin has also died. I have no idea why it seemed active and healthy all along and was doing a grand job of keeping the substarte clean and sifted. No answer to this one. One of the Mithrax is also MIA. The female.

I’ve got crabs

More critters arrived today from fishmansfrags: 2 pom pom crabs (Lybia tesselata). Tanks probably a bit bigger than most would suggest for these tiny little beauts but as I have pretty open rockwork I thought I’d give it a go: …and a porcelain “crab” although it is a decapod it is not a “true” crab (Decapoda: Porcellanidae): Both of these I believe are truly reef safe. … Read entire article »
