Jewel Damsel behavior.

[ShooterRick]

I picked up my Jewel Damsel for my tank yesterday. All fish in this tank are aggressive. I notice tonight she was consuming lots of diatom algae. I had an outbreak and introduce a clean up crew several days ago and it is going well with that.

I also notice tonight she will pick a snail off the glass and drop it at the other side of the tank from which she is feeding on the diatoms. ?? Is this unusual?
