Yeh. He seems to start to come out a little more after the light has been on for a couple of hours. Then when the light goes off, it's back into the skeleton for the night.

Mine retracts at night, the tentacles become thinner and much smaller, though you can't see the skeleton, and depending on how much I annoyed it during the daytime (cleaning the glass etc) is whether or not the sweepers come out, if I haven't disturbed it they generally don't...

The only time mine retracts as much as in your picture is when it's been taken out of water...

Seaturtle, these are fine but you forgot to mention to the most influential; nitrate and phosphate. They can upset corals preventing growth over the long term and extension of polyps over the short. As long as the absolute value is <10ppm for nitrate and <0.03ppm for phosphate you should be ok, however I have noticed that it is sometimes the relative concentrations (i.e the different between the LFS system and your system) which is the most important variable. It is encouraging to hear it likes the move to the bottom and is certainly suggestive that placement and water flow are the key parameters here as opposed to chemistry. I think your best bet is to see if he settles at the bottom and slowly move him up the tank over a number of weeks to see where he likes.

Ok. Will check that out tonoght and report back to you. I was also thinking of adding in a phosphate reactor soon. Do you use one of these?
