Stocking 55 Gallon

[Dekz]

I'm currently in the process of converting my 55 gallon tank from planted freshwater to saltwater FOWLR.

I've ordered a BUNCH of equipment and hopefully next week I'll be filling the tank with water and live/base rock.

I want to start planning out the livestock now even though I know we're at least a month away.

Things I am definitely interested in:
Bangai Cardinal - how many of these could I go for? Could a pair potentially breed? If so, how can I identify sex?
Clownfish - same questions as above
Flame Angel
Six line wrasse

I also really like Firefish but I think they might be too timid for a tank this size and the fish that are going to be in it?

I would LOVE a Mandarin Goby but I've read they are quite fragile?

Any incompatibilities so far, suggestions?

cardinals I believe are just as timid, and are also a quite boring fish. They just kind of float... from what I have seen anyway.

I think understocking is always better than overstocking. With a pair of clowns, the larger will become the female. A Mandarin Goby would need a lot of copepods to live on. A lot of live rock and a mature tank is best for them.

i agree on the cardinals. i don't know what people see in them. they remind me of a fresh water fish.
also, the 6 line wrasse. they are a neat looking fish, but you can put any of the reef safe wrasses in your tank. look here-
