There are a couple of possible pitfalls to keeping these tank bred fish:
1. Just because they will eat pellets, doesn't mean they will know how to forage for pods between feedings. Mandarins need to eat pretty much constantly. If these fish still have the instinct for hunting, they will still need a quantity of live rock and/or a specific breeding ground for pods such as a refugium.
2. Feeding pellets once or twice a day will not sustain a Mandarin. They are timid eaters and they can't compete with other fish in your tank for pellets. Unless you have the time and patience to target feed these pellets directly in the vicinity of the Mandarin many times a day, I'm not sure the survival rate of the tank bred fish will be any better than wild caught ones. It may be necessary to overfeed your tank in order to keep these Mandarins alive. I'd like to hear opinions about these Ora fish from other reefers who are successfully keeping wild Mandarins and are familiar with their habits.
