Hi again reefers, As part of the Pringle Lab closure at Stanford, we also have some anemones I would like to rehome. First of all, since we use Aiptasia (Exaiptasia diaphana) in our work, we have TONS of Aiptasia (literally 1000s). Obviously no one sane wants these in their tanks, but if...

I looked up the palys that Hawaiians used for their spear toxin, and the likely species is Palythoa toxica. However, the description and images of P. toxica don't match the paly's I collected from the Kane'ohe Sandbar. There are also no reported sightings of P. toxica on the Kane'ohe Sandbar on...

Thanks again for picking everything up @MichaelB! The empty tank looks like this now: I'll drain it when I'm back from vacation the first week of July. Then I'll make a new post here with all the equipment up for grabs. The paly rock in the last picture in @MichaelB's last post is covered in...

@MichaelB picked up everything. But you can still get some at the upcoming frag swap! I will post the equipment here for free in early July.

UPDATE: @MichaelB picked up everything. He says he'll bring most of the corals (and live rock) to the upcoming frag swap. Thanks and I hope they all do well in your tanks! Hi everyone, Professor John Pringle at Stanford University is retiring, and his lab is shutting down. That means we need...

Update: big AES sump and working chiller are gone. @BAYMAC and I are working out a time for him to pick up the remaining sumps/wet-dry filters and canister filters. Everything else is still up for grabs.

I had no idea Caribbean curlique anemones (Bartholomea annulata) were popular in the aquarium trade! We collected a few in Hawaii last year (all of which have now died) and a couple more in the Florida Keys this year as part of a big sequencing project. Honestly, the collection was accidental in...

Everything was either given away or trashed. Thanks to those who came to get something! Hi everyone, The Pringle lab at Stanford is compressing into a smaller space, so we need to finally get rid of a bunch of old equipment we no longer use. Everything is free to whoever can come get it first...

Unfortunately I've already given away all the corals I had to give. I could still scrape some Kenya Trees out of another tank and maybe a couple blue Discosoma mushroom corals, but I'm not sure it is worth your time to come get them unless you're really closeby... Yeah, there is one...

Another update on Berghia breeding with pics. This time I used a microscope with attached camera, rather than my phone held up to a microscope eyepiece. Some of the eggs separated from the ribbon, allowing a better view of the embryo shortly before hatching: After hatching, the larvae look like...

So far, the 5 Berghia nudis given to me by @JVU have grown and appear healthy. They've laid quite a few egg ribbons and I've noticed a number of tiny nudis crawling around, although all seem to disappear within a few days. Maybe they are just hiding somehow. Anyway, I took a few pics for...

Exaiptasia diaphana (the most updated scientific name for the anemones most reefers call aiptasia) are a "cosmopolitan" species, meaning they grow in tropical and sub-tropical waters all around the world. It appears that some populations have been reproductively isolated from each other for a...

Thank you for your offer! For now I'm limiting my coral experiments to Acros and Montis. It will be a while before those experiments commence, as I need to give the Acros time to grow and I need to perform more aiptasia experiments in the meantime. I'll let you know if I decide to try these...

Wow! That's really salty (~46 ppt)! Interestingly, there is some literature suggesting that higher salinity can protect against bleaching, but your point is well taken: what is true for aiptasia is not necessarily true for reef-building corals. That's why I want to repeat my experiments in...

I'm critically testing the dominant hypothesis about how heat-stress causes symbiotic cnidarian bleaching. I refer to this hypothesis as the reactive oxygen species (ROS)-induced bleaching hypothesis. The original idea, first popularized by Michael Lesser in the 1990s, was that the...

The aquaria are in Lane building. Our lab (John Pringle's lab) studies cnidarian-dinoflagellate symbioses. We mostly work with aiptasia in lab, but some of my lab mates have done work on corals as well. The aquaria are primarily for enjoyment and outreach (showing a bit of diversity of corals...

These softies have taken over my aquaria at work and I need to make room for some hard corals. These are big, healthy, and easy to keep soft corals. I'll rip them off the rocks for you when you arrive. See the pics. Pick up in the Stanford School of Medicine, although I go to the East Bay pretty...

My 10 gallon AIO tank at work just has a 1/2" drain drilled about 1/2" from the top in the back compartment. This is ~1/2" above the normal water line in this compartment and about equal to the water line in this compartment if I turn off the return pump. Tubing connects this drain to a 5 gal...

I wasn't accusing you of referring to it as an infection @IOnceWasLegend! I just wanted to make it clear to others that the link you provided did not give any evidence of an infection. I'm not sure of the exact number of coral genomes that have been sequenced, but we have sequences for at least...

I would caution against calling this an "infection", as it is not clear that any infectious agent is involved. This may simply be the corals responding to some change in conditions by expressing genes for GFP (or another fluorescent protein/pigment) that they already had in their genomes, like...
