BTA Acting Weird

Posted this in the general forum as well, figure someone here might be able to help out as well.

Came home today and saw my BTA doing this

What the hell is it doing?

It is spawning, back when I had BTAs they would do that once in a great while.

I wouldn't be too concerned, but it wouldn't hurt to run some fresh carbon, and do a water change if you have some water already made up.
