So I have had my first RBTA in the tank for a little over a week. It settled high on a rock opposite the light, and likes to stretch out over the top of the rock towards the light during the day. Seems happy, hasn’t moved since it settled. No bubbles, just stringy tentacles. But seeming normal.

Today, I see it twisted at the base and closed up. I hadn’t fed anything, so seemed odd. Searched the forum and found a few examples of similar behavior, and that it was nothing to worry about.

Sure enough, and hour later, it’s back to stretching out, tentacles blowing in the flow from the return.

Another hour later, I watched it twist at the bases and essentially collapse.

Is it preparing to split? Or just being a nem?
