I don't know about your's,
But a few of mine are such attention whores.
I can't even look in my tank with out someone coming up face to face with me. LOL

More like prisoners contemplating on how to murder the warden and make their escape. :razz:

But ya, mine do the same thing, every evening they start to swim around the "feeding area" awaiting their meal.
