Well i'd like to seed my tank with pods so Chaeto cuttings from people would be nice.
As far as corals... almost anything would be helpful. My tank is fairly empty. I have a couple cheapo frags from the frag farmers event back in early march, basically a couple zoa polyps and a frog spawn 2 other small frags which I think are a frog spawn, and 2 mushroom frags.
Different color zoas, kenya tree (I hear they are cheap), leathers, pretty much anything I'd be interested in.
I don't know if anyone has some ulva sea lettuce though but I'd like to grow some of that in my refugium to feed my hippo tang.
