OK it was not easy, I took this picture through a jeweler's loupe and 2 magnifying glasses all hand held, try that sometime.
Of course here the thing does not have the polyps extended because I sucked it up in a baster looking thing and put it in a tiny dish. make believe the polyps are extended as they do in the tank.
I Lied, it is an eigth of an inch, not a quarter.What do you think the chances were of me finding this in a 6' long tank?

That little Bumblebee gobi is living the good life. He now seems to eat a variety of foods and judging by his stomach, he is also finding other things to eat. He also eats live baby brine which I am glad about because I feed those twice a day.
If I have time I want to get a few more of these gobie's today.
They are a nice colorful addition to a reef although they are more of a brackish inlet or bay type of fish. I just don't tell anyone and they think he is a reef fish. He thinks that also, I think

I just got two more of those $3.00 bumblebee gobies. I am acclimating them to saltwater now. I love those things. Maybe they will spawn, everything else is, why not?

Hi Paul
Your tank is very interesting and it is a living source of information, a living research laboratory.
If you succeed, and I hope you do, it will be another breakthrough.

Here is some information about Bumble Bee Gobies that I found by searching the internet.

Brachygobios xanthozona & Brachygobius nunus

Bumble Bee Goby

Bumble Bee Goby Brachygobius xanthozona

Bumble Bee Gobies

Breeding Bumble Bee Goby

The several species of Bumblebee Gobies come from Asia, where they are found in salt water swamps and stream estuaries in India, Thailand, Indonesia, Borneo and Malaysia.
Look forward to read more from you.

Cheers Paul
Pedro Nuno ;-)

Pedro, thanks for the links, I read them all. They seem to think these things are hard to feed. They seem to do fine and luckily for me and them, they eat what I give them.

Talaverus, a member on another forum was kind enough to test my water for me. I was very happy as I don't usually test for anything and was surprised by some of the readings.
The last number in each line is my reading, the number before it is the amount present in seawater.
For instance my calcium reads 516, seawater is 418
My copper and zinc seem a little high, but I figured that.
My nitrate is 5, not too bad
Everything else seems OK.

Thanks again Stuart.

Kathy, Why what? Why are they high or why did I assume they were high?

Last year I lost most of my corals to what I think was zinc orthophosphate from the water company so I assume there is still some zinc in there. It is low enough not to cause a problem but still higher than NSW. Copper was used in my tank continousely for years many years ago. I don't know if any of that copper is still leaching from my rock (I doubt it) or if it is coming in with my NSW or through my resins and RO. which I also doubt. It also is low enough not to cause a problem.

Is this someone who does this for other folks for a fee? That's a LOT of testing!
Yes he works for a water testing company in Canada and he offered to test my water for free because they never tested water this old before.
It is a lot of tests

Yes to both :)

What water company is in your area Paul? Did any of the other reefers near you (if you know) have similar issues?

Do you think the bottles & cans and other interesting items in your tank add to the metallic compounds in your water that others may not have in theirs?

Kathy, this happened twice to me in 30 years. The large LFS a few blocks from my house had the same problem and they still have it. I now have filters designed specifically designed to remove lead and zinc so it should not be a problem again but regular ro/di does not remove enough of these elements if the initial supply is very high.

As for the bottles, they are all very old and most of them I found underwater, they are inert, I only had a can in the tank for a few months and that was aluminum. (it was covered in fiberglass resin)
My iron is not that high and my iodine is zero which surprised me being that I dose Lugols Iodine.
The zero iodine level means to me that something in the tank is using iodine.
My town regularly uses zinc orthophosphate to control corrosion in the town plumbing. Brass plumbing in my town corrodes fairly fast which this is supposed to correct. They add it fairly close to my house. I don't know anyone near my home with a saltwater tank
