First of all, great choice with the mando, i love them, super colorful, hope its nice and fat. Second, a pair of clowns would work well, because mandos do their own thing and bother no one, and clowns can get sort of aggressive if you add them first, so later allows other fish to establish their territory. Even tho mandos dont have territory and do as they please lol. Royal gramma would also do well, not very aggressive but can be if threatened. Blennies and gobies are very peaceful, so those would make excellent tankmates, I would suggest tailspot or bicolor. Watchman goby snapping shrimp pair would also be awesome, the symbiosis in that is awesome to watch. Id go with the clowns if i didnt have any already, they have lots of personality and basically an essential in any reef/SW tank.
Go with ocellaris. They come in more varieties and i find them simply more attractive. PLus ocellaris stay relatively smaller.
May i recommend either the nearly naked, snowflake, and my personal favorite the midnight lightning?
