http://www.aquacatcruises.com/ Totally worth the cash. The live aboard dives that Eric Borneman is 'leading' after MACNA this year in the Flower Garden Banks, Texas' coast, will be similar, but not quite as extravagant/lavish. Still should be good diving.

My next place to visit might be Bermuda's research station.
To bring this back on course: I mentioned Centropyge argi as possible seagrass residents.. well, they are definitely good candidates for the right setup. I tried several LFS residents as well, including other argi, and argi-similar species. All are good, or at least the individuals I tried were.

My little one picks at teeny patches of glass and diatom algae, grazes on pods in the bed and runs to the front glass to beg for algae flakes. Model citizen, no nipping of Chaetomorpha, Ulva/Enteromorpha, Halymenia, Padina, Caulerpas, Halodule, Halophila, Thalassia or Syringodium. She's great!
