Group order for Tang Heaven - NO MORE ORDERS

[Rikko]

I threw about 1/4lb into my display, thinking it would sit around for a while like the big lumps of chaeto and halimeda I sometimes throw in do.
I can't find a shred of it after 4 days.
My long spine urchin probably did a number on it, but I see a pretty big gut on my normally-skinny yellow tang. My scopas looks a little plumper than usual, too.
