There is no easy fish to keep that is difficult to feed. Reminds me of the old Seinfeld routine he did with a car rental company that gave his car away. It's not the taking of the reservation, it's having the car when I come to get it. If a coral or fish is easy to care for, ie; feeding and water parameters are acceptable with ordinary equipment and upkeep, then it is a easy fish/coral. If, on the other hand, you have to feed live food as the sole source of nutrition, then that gets out of hand for most reef keepers, even if they are dedicated, they go on vacation, get sick, or bored after awhile and the organism doesn't care, it dies.
