Rygel - lawnmower blenny named after the Rygel XVI, Former Dominar of the Hynerian Empire. Mostly because he looks like Rygel, and acts a bit like Rygel (and eats an awful lot too ....) although to my knowledge

Half-Pint-O-Tang - YT named by EmB ... he's not really half a pint anymore though, a bit more I'd say.
I call my RSSF tang "PleaseComeOutAndStopHiding" but it's a bit of a mouthful.
