visiting Holland
We visited Peter and Anne's house...
to celebrate my dad's birthday. (Here is Mom cutting the special cake she baked.)
We enjoyed the nice (relatively cool to us) weather by going biking, including an extra-long ride today.
We went to the beach a couple times, and I went swimming while Brian made some carefully crafted sand castles.
We introduced Mom and Dad to Rockband. They both gave it a try and decided it was hard and a good way to learn rhythms. Dad especially favored the drums.
Also while we have been here, there has been construction during the day. As you can see, the siding is on the 3-season porch and it is really looking like a part of the house now. The inside is also almost complete, and the floor goes in next week (I think). Pretty cool!

A few pictures of new coral
This next one is called a large polyp Duncan's Head. It was the most expensive coral I've bought but I was surprised they had it and it was half the price I expected from shopping for it online for a while. This first picture is of it during the day. This coral is one I purchased.
As you can see in this next picture of it, taken at night, it has nice neon green in its center. It is a stony coral so in time it will grow more branches (if it does well, that is) and more polyps. If it grew more and I was inclined to, I could use bonecutters and cut off a branch and give it to a friend, trade it, etc.
Finally, here is the other coral Hanneke bought. It is called a sun coral and the picture is taken at night because the tentacled polyps you see only come out at night. This is Hanneke's coral and it is the first one we have that requires target feeding. Our others are primarily photosynthetic, though they also filter feed. This one is carnivorous and needs to be fed brine shrimp or phytoplankton. Han does both with a turkey baster. It's a pretty cool coral.
Here's one last picture of our small tank overall. In it you can see the bright orange color of the sun coral under the lights. There are some snails crawling up the back. You can see that our candycane coral, the purple one on the right, is repairing itself - those lines of goo coming off it are it self-repairing.
See you all soon.

Hanneke in the news
SciGirls Story
Pretty cool, huh? She put a lot of work into the camp.

Fifth of July (Han)
The first thing we did once we arrived was get out of the car and take a hike. It was needed after the long ride. The trail led us through a sandy area of wild Florida, with a marshy zone to the right and many types of trees and shrubs. By the time we got back to the car, we were pretty hot.
The clouds were forboding, but the sky above us was bright blue, so the majority of the storm stayed over the mainland.
We had a pleasant lunch on the beach (sandwiches, pasta salad, grapes, vegis), watching the clouds, the waves, and the sea birds. The bird below is the one who hopped nearby and got rewarded by Brian with a bit of his sandwich. Immediately afterwards, a couple more birds hopped hopefully in our direction.
Brian and Vincent spent a lot of time sitting on the beach, talking and watching the water.
Meanwhile, I was swimming and looking for seashells. I even saw a tiny fish, who swam up to me when I was standing in shoulder-deep water and seemed curious about what I was doing there.
After a while, I convinced the boys to get in the water too. We swam for a while and got tossed around by the waves. (Here again you can see the clouds over the land, contrasted with the clouds over the water.)

Fourth of July update (Brian)
Then we hung out around the apartment some. While Hanneke was working on things outside, I did some gardening. I put in some new flowers, moved some grass to a new area, put in what will later be part of a small solar-powered waterfall, and did some trimming of other bushes. Here's the waterfall/pond, which is just a muddy hole for now:
Here is a bed of flowers Hanneke bought and I put in:
And here is a lantana bush we put in. They reportedly help repel mosquitos, but in any event they look nice and require little water:
After gardening and cleaning up, we went to a dinner where one of Hanneke's friends proposed to his now-fiance. Here's a picture from that:
Finally, we came home from dinner and lit off a few fireworks that we got in a pack from Walmart a month or so ago. The 1 minute video below is of the main one. It was a cheap pack, maybe $10, but I was surprised that Walmart-level fireworks do what the one in the video does. It was fun:
Not much else to report. In other good news, additional research indicates that only Palythoa species of the Zoanthidae genus potentially contains palytoxin and zoanthus species, which appears to be the kind we have, does not contain it. Still need to look into that more.
Hope you had a good Fourth. We look forward to seeing you all soon.

Recent events and an unfortunate turn in our tank
Work has been going pretty well. I completed a major assignment a few weeks back and it was very well-received. I have lost my perception on what is "average" work and what is "excellent" work it seems. I felt my work was better than sufficient but it was deemed impressive by multiple individuals. For whatever reason, as a result of the compliments I feel like I should have worked harder instead of feeling satisfied that it was helpful to the Court. In future news, I have an assignment for the coming months that I predict will be divisive because it's a difficult issue of some importance. We'll see how it goes.
In an unfortunate turn of events, I recently learned that some of our coral are a potential health hazard. The problem corals are our two zoanthus polyp colonies, the green and purple things from the videos on the top rocks. I had done research on zoanthus (species)/Zoanthidae (genus) but never came across any information indicating they were dangerous. As it turns out, some specimen in the Zoanthidae genus (which includes palythoa, protopalythoa, and zoanthus species) contain a neurotoxin named palytoxin. Palytoxin is an incredibly complex molecule that is also, depending what source you read, either the first or second most toxic organicly-produced compound on Earth. It is fatal in humans at a dosage of less than 5 micrograms and fatal 50% of the time at a rate of less than 100 nanograms/kilogram. While it's only released defensively, such as when cutting zoanthus, I would never have bought something that has such properties if I had known about it. Zoanthidae are remarkably common and people all over the aquatic trade frag them (i.e. cut them). I can find almost no reports of serious injuries or deaths. And given that some major retailers don't even mention the risk (aka all of those I shop at do not mention the risk at all), I have to believe that the information I have so far is incomplete. Still, I'm not happy to learn this. It will very possibly lead to my carefully getting rid of the Zoanthidae we have. For more info of the chemical sort, go here: http://www.cbwinfo.com/Biological/Toxins/Palytoxin.html.
This is an unfortunate development; zoanthus are by far the most impressive coral in color variety that I've seen. But it's just not worth the risk.
