Clownfish

[Steve-O-]

So my clowns started to spawn again after there move into the smaller tank but i have noticed some strange stuff happening. I have been finding shells and small chunks of live rock outside my tank. I keep putting them back in the keep finding them outside again. So this time i plopped the large shell back into the tank and watched.

My orange clown would grab it from the sand bed go far back as possible swim up real fast and spit it out of the water!. She then right in front of me grabbed my baseball sized candycane grabbed it and tryed the same thing but it was far to big and heavy.

Anyone else fish do this? Gonna record it.
