I wish I didn't have to use the flash to see the goby or that glare wouldn't have been there! He hangs out in there all the time, except now the polyps are closing in. But hey, the closer the polyps, the cooler the pic!
Those are the "flourescent pink" zoo's from tonga. Order pink polyps from any of your tonga suppliers and you'll get them, they're usually grey w/ a hint of pink. The last few batches we got came down w/ Borneman's "zoanthid condition 2" which results in the loss of the entire colony every time. Bummer, since they're really nice zoos.
They get a nice metallic pink under my 400w Iwasaki's though, probably look better under radiums or heavy actinic.
