I dont have any, mines not special, just what ever grows, I did once have a white polyp with fluosecent tips grow in there, that was cool, it was either a shrrom, zoa or anemone but he floating to the back of the take I cant find him
I decided one day that I would catch some pods and place in there, let me tell you, if anyone were to of seen me doing that they would have laughed their tail off. The only other things I have in mine are 2 mini brittle stars, a few brittle worms, some mini stars with varias legs(from what I'm told they spit that way) and a really pi@@ed off snail. I need to get a picture of that snail now that I think about it, it sure does keep the sand shifted.
I hear you, catching pods (espically the evil kind) is a huge pain in the butt. Sitting and checking your tank hour after hour to see if something else crawled out is so infuriating.
check out www.ipsf.com and www.inlandaquatics.com for fuge critters. I believe inland aquatics has a microfauna package that you can buy with preselected fuge critters.
