As promised, here are some pictures of the GBTA's and my tank ...
These two anemone's have been side by side since they split about 11 months ago (shortly after I redid my tank setup). The one on the left is the biggest GBTA I have at ~ 2" diameter.

Here are the same two GBTA's only with the flash --

And a top-down shot ...

Here's a full tank shot with the pumps turned off (yeah, I know I really need to clean my overflow box and the glass - especially the back). Two GBTA's are near the upper right of the rockwork (the ones from the previous pictures). The other two GBTA's are on the rock on the sand in the middle of the tank.

This is a rather poor picture of the anemone from the middle of the tank.

And finally, this is the GBTA near the sand. You can really tell how off the white balance is by looking at the sand ... yikes! Still ...
