Thanks for all the advice. I really like the one about the picture

Unfortunately my earlier assertion that both my BTA and I had come to understanding was incorrect. Wonderlust has seemed to take the creature to the back aquarium wall near the surface of the water.

This morning when I found it I quickly moved my K4 to the front (not happy with that) to prevent a mishap.

I think it's moving around so much perhaps looking for food. I've sprinkled some in its maw while feeding the other fish but I haven't fed it any larger pieces yet. I've been waiting for it to settle down. Could it be looking for food?

On a side note, my larger clown has been looking at it...
