What makes a BTA actually expand his bubble tips?
Does that mean he's happy? Or trying to suck up more light?
I have one in my tank which is much too early but I got him in trade so I figured I'd give it a shot and watch him carefully. He seems to be doing great, found his happy spot in the tank and expands pretty huge. He'll eat food from my hand and my clown has been hosting him. I'd say everything has been going as described for about a good two months. Not too shabby for a 4 month old tank. But he almost never has any actual bubble tips. All his tentacles stay pretty thin. Some start to form a bubble-ish tip but not much/many. Any clue on how I should be reading this behavior?
Oh, and the spot he picked is at least halfway up my rock work. His foot is attached underneath a rock that is almost like a flat bridge. He stretches way out and fully expands for most of the day, almost on top of the same rock, sucking up rays, then when the lights go off he retracts into a ball under the rock and goes nighty night until the lights turn on again in the morning.
And like I said, this has been the same day in and day out for a good two months.
