Some fishy photos...because I was practicing in preparation for the photo seminar this weekend.





Am I supposed to have the fish swimming to the left...or to the right?

I think your supposed to mix it up.

From the second pic...it would appear your urchin is getting quite big or very close in the foreground.

Yes, that hatpin urchin is probably 10" in diametre. When I got HIM, he was maybe 2". There are two urchins in the tank. One hitchiked in on the LR. The hitchiker urchin is smaller, with generally shorter spines. That one has grown from <1" to about 3". Both eat coraline.

There is a display of Bengaii Cardinal Fish with Hatpin urchins at the Vancouver Aquarium. The young Cardinals are supposed to hide in the urchin spines, but I saw no evidence of that in the display. None of their urchins were as large as mine, and they are clearly the same species.

well obviously they are getting their fill of coraline.....

Big day today. Spent nearly 3 hours replacing all my bulbs. I've got to Geisemann 13000K. A job that should take 5 minutes takes 3 hours in part because of the foolish design of the Aquamedic light fixtures. Changing the halides and flourescents requires removal of 20 screws on each fixture.

Is it Aquamedic's fault?...or my fault?...or just the way it is?.... I cannot get a 250W MH DE bulb to go into the fixture!!!! It might take me 30 minutes or more of fighting with the bulb to finally get it to click into place. I break the ceramic tab on the bulb about 50% of the time.

Very frustrating job and I'm glad I don't intend to do it more than 1x per year. So far, I'm happy with the look the new bulbs are providing.

The babies do hide in the spines of the Diadema urchins. They don't do it for very long though, just while they're really small.

Here's a group of photos now that the new lights are in. There are some new fish in these shots if you look closely.
