I haven't read his book, but writer David Dobbs is publishing large excerpts of it on his blog about the 19th century debate over the origin of corals. The first two excerpts are already online: Reef Madness Begins: Louis Agassiz, Creationist Magpie The One Darwin Really DID Get Wrong...

My new D-D Refractometer arrived today, and it is definitely a HUGE improvement over my old one. I gave it some "light abuse" and the calibration didn't drift like my old one would. I also found it easier to read, and it has a heftier feel like the lab refractometer I used at an old job. It...

When I started school there nearly 12 years ago there was a reef tank in my department at Storer Hall. I particularly remember a carpet anemone with a pair of clownfish in a corner of the tank. Even then it never occurred to me to keep reefs.

That looks really cool. I would like to be kept in the look on that one and maybe a piece of it later on :) Alex

Seems like hybrids have been screwing with me for half my life, but if it were true I would feel kinda lucky in this case :)

We exchanged emails already, thanks.

I gave a piece of this algae to Eric Henry at the OnSight booth at BAYMAC. The tentative ID is a species of Gracilaria, but he said that he'll send it to another colleague to get a more affirmative identification. It's kinda exciting since we may finally figure out what this is. The red...

Redundancy? Problem solved: I picked up a CPR Aquafuge at BAYMAC, which is way more spacious than the AquaClear and the closest I can get to a sump (except it's elevated). This meant reconfiguring my tank, but I finally installed a Koralia for most of the movement while the Aquafuge's...

"Hammer frog" can't end well :) I know, I just remember from when I used to ID plants, I would have to wait for the damn thing to fruit before I could key it out but show one leaf to someone who's studied that group for half their life and they can name it in an instant. Euphyllias seem to...

My first BAYMAC and now my first Maker Faire, whoohoo!

Thanks again Tim for the mini anemone! Question, are the mini anemones prone to playing dangerously with powerheads? Usually when I read about the disaster/shredder stories they involve bubble-tips. Thanks. Alex

I don't think that's it, but then again common names aren't very reliable. I've heard of grape coral refer to Euphyllia cristata, which I also have but looks distinctly different from the photo above. E. cristata is more like a frogspawn without the multiple tips, while the photo above (and in...

Any Euphyllia experts here tell me what I have here? I long presumed that it was a hammer, but the tentacle shape doesn't look "quite right." The tips have a fatter, rounder shape than the hammers than I'm used to seeing. I'm thinking it's just a funny-looking hammer, but then I read about this...

And an open cut to test for palytoxins? :) So two votes for D-D, and I also read on other forms that Vee Gee / Vital Sine makes a good (but pricier) one. Whatever, as long as it stays consistent long enough and can tolerate the trauma of being gently placed on a table, even a...

Sounds like I have a POS; it's from Marine Depot. If I'm extremely careful I can get consistent results more often than not, but it's been too frustrating one too many times. So the next question is, what would you recommend for a non-shitty refractometer? Is the one at Bulk Reef Supply any...

My refractometer has trouble holding its calibration. It'll shift by a couple ppt if I accidentally bump it against something in my cramp room, or even after putting it down on the table for a moment. Arghh. I've used lab quality refractometers back when I used to work in a lab and I don't...

I'm too lazy to post them inline, but here are my photos from yesterday.

This was my first BAYMAC and it was definitely fun. I met up and exchanged corals/snails with some members, I got a nice green Caulastrea from the BAR frag sale, and talked to some interesting people. Onsight was probably my favorite booth there and I enjoyed nerding-out with Leslie Harris...

I took some photos yesterday, do you have a preference where I post/send them?

I know this is last minute but I plan to donate a frogspawn frag. It's the only one I have ready and available.
