Finally, do some research on the feeding habits of a fish before you bring them home.
I thought about "smashing" some tubifex worms into my live rock for the Cardinalfish. After much research, come to find out, Cardinalfish normally will only take food from the water column. I am sure that if they got hungry enough that they would eat from the live rock and sand.

You are correct about nocturnal feedings. Cardinalfish prefer to eat with the lights out !

Thanks for the information Gary!
