I have a 55gallon standard tank, with 260 watts of PC with 10ks and Blue actinics

I feed my BTA every 3-4 days shrimp, and i have never seen it go back to a bulbous state, why is that, it looks nice, but i never see an actual bubble tip .. should i be worried

Dave,

No need to worry about that. This particular phenomenon is only obseved in captivity and there are still no conclusive evidence as to why this may be happening. Some researches say that light intensity plays the most important part in the bulb production( or lack there of) but I personally fail to see it in my tank with pretty intense metal halide lighting over it. Perhaps it needs to be even more intense but I am not sure, nor am I about to experiment.
As long as the animal is healthy,ie. grows and reproduces, I wouldn't worry over this. In fact, my E.quadricolor , and I have quite a few of them, exibit those bulbs every morning while tank is lit only with actinic fluorescent bulbs. As halides turn on the bulbs slowly disapear. I am not saying that less light is what does it either, some people have very intense MH lighting over their tanks( 400w) and their anemones have bulbs all of the time. Tentacles are much shorter and all that. Perhaps locality where they were collected has something to do with it, perhaps food, maybe even current in the tank. I just don't know.
