Love the rock flower nems.
pacificeastaquaculture.com often has a lot of very colorful ones for sale. I've been tempted but am weary about nems in general.
These look amazing, though:

Great work on the tank. Love built-in setups.
yeah, they are neat but rather expensive from the website. he visits our local reef club meetings and things are typically 50% off or so and then it's a good deal!
i got these rock/flower nems from djfrankie on ebay. we had a shipping delay and he handled it like a pro and refunded my cost. they were only 29 bucks through him, one cost for multiple items shipped, and everything was bigger and arrived healthy looking.
don't be worried about rock/nems. they rarely ever move from where you put them. they are much easier to keep than a BTA or similar.
