No, there really isn't. The same ideal that applies to most corals applies to zoas. The more light, current, and gallons you can provide the better.
That being said, if I were to get another tank I would go with something that was wide like the 40g breeder tank. The larger the footpring the more space you will have to set your frags out. I would light that tank with one or two MH lights because they are 36" long. I would also try and place my powerheads on some type of wavemaker so that the current was consistent.
Like I said before, same type of care as any other coral. Does that help?
