It hasn't changed much. It is not extreemly sticky, but pulls the food deep into its tentacles very quickly. I am feeding it small pieces of silverside everyday along with what ever food it catches that was meant for the fish. I will cut back on the feeding once it gets more of its zooxanthellae back.
It fills the rock spaces during the day (which I like). At night under the moonlights, it expands into a big circle with more defined bubble tips. I'll see if I can get a pic tonight.
FWIW: it is in one of a tandem of 20 gal tanks plumbed together, that have been up for 10 years. It has been a very good home for BTAs in the past. I just sold the last one (had it and two others for over 5 years) to make room for the new one.
Each tank is lit by 2-65watt PC bulbs. I just switch to Dual Daylights and Dual Actinics from regular 10ks and actinics. They are more expensive, but my eyes and my animals seem to like the change.
