As i am setting up my tank piece by piece, feather duster, fish, anemone etc, i am finding out that you have to feed every individual invert / creature which is no supprise. But i am baffled by tanks that have so many clams, inverts, and a plethora of live stock! I was thinking , if you have to feed each individually, how do you possibly keep track of everything and feed everything correctly?!? the onyl way i could possibly even fatham doing this in a tank that is full, would be to keep a list of days that livestock / inverts should be fed and how. Is this as diffucult as i am thinking ? What do these large tanks do ?
