This is not really true. If you take a full frame photo with a 40 mm and again with an 85 mm, both at the same aperture, and then crop the 40 mm image to match the one you got with the 85 mm, the apparent depth of field will be the same in both images. I prefer the 85 mm because it allows me...

I've had my borb for three years, and we are just finishing its third try at dying. Each time it stops eating, hides in the rockwork, becomes pale, shows some raggedness in its fins and once, even spent 4 days lying on its side sort of gasping. After a week of this it takes one mysis shrimp...

Yep, I finally eliminated all of the Aptasia in my 40 breeder system. Last week I returned to my office to find a flood on the floor and the sump completely full of water. It seems that the ATO stuck in the on position and pumped RODI into the tank until the timer cut it off, but the sg in the...

The Tin Eye can be a very useful site for tracking down "re-used" photographs on the web.

I think that's it. Thanks. We'll pass - it is a little too aggressive for my set up.

I just saw what was called a quavipatum wrasse. It was about 3-4 inches long. Out was pink and green. I can't find any information about such a wrasse. Anyone have any ideas? Sent from my SAMSUNG-SGH-I727 using Reefs

I have been doing research in the biology of aging for 40 years, and can tell you the life expectancy of pretty much any animal, but not fish in captivity. There are just too many variables, including temperature, diet, water quality, etc. That said, most long-term aquariasts have had at least...

I have a 220 oceanic FOWLR, and just put on a 1/4 hp Arctic chiller - it seems fine. However, since adding the chiller I notice that the tank heats up even faster than before - probably due to the heat from the Mag 18 that circulates the chiller. Nevertheless, the tank stays between 77 and 79...

Don't get caught up in the Nikon vs Canon debate. Both systems are excellent, but Nikonians will be all to happy to tell you what's wrong with Canons, and the Canon folks will be just as happy to bad-mouth Nikons. The main difference, IMHO, between the two is size/weight/ergonomics. I am a...

Ha Long Bay, Vietnam with a D-80 A happy frog, D-80

Current has gone out of the chiller-making business. Their entire line has been discontinued.

When I have moved fish and corals in the past I have always mixed some Prime or Amquel with the water. Your animals are going to be in a very confined environment for an extended period of time - the pH and ammonium levels will change, and these two products will help[ buffer pH and mitigate...

Thanks for all the warm welcomes. I'm glad to be here. My son and I just spent the weekend breaking down my 110 and putting the fish into holding tanks. We also put two floor posts in the basement to support the floor for the new 220. When I start the build thread I'll post pictures of the...

At the going price for one of these, I think it is unlikely that many people have had experience with schools of them in captivity.
