Will the tips color up when the coral gets more sticky and more acclimated?
I've noticed at night it really retracts into the skeleton, a couple of hours after lights out. Is this a normal thing...My branching hammer doesnt retract to the same degree.
Looks great Nick!
The tips will probably not change color, they might depending on food provided. Mine has a faint hint of pink in it, and I hoped that over time it would become brighter but it has remained the same, even with very nutritional foods.
Regardng being "sticky," I believe its a hunting mechanism as well as a sign of good health. Its a sign of good health in that its wanting to hunt (eat); Like a fish, if its not healthy it wont be as prone to hunting (eating). After a large meal though, they do not seem to be as "sticky, " leading me to the thought that they control this mechanism some how.
Most of the time mine retracts almost all the way into the skeleton, but like Ryan said, they do funky things

. When fed, mine stays almost all the way open for a few days, then once foods been well digested starts to close up more at night.
rduong89, FWIW I've noticed that they prefer smaller food items, like mysis, or my elegances' favorite, Rods Food. I believe its easier for them to digest, and has a varied nutritional basis for them to utilize. Now days if I offer mine a silver side, it will start to eat it, then "spit" it out.
