Tank will be a 180 Gallon mixed reef (6x2x2), Fuge will be a 40 breeder filled with rock, sump size is unknown, but I'm guessing around 20 gallons of water between the different sections there. Lid will be made of ¼" mesh, and tight fitting to keep the wrasses in the tank.
I had a hard time coming up with this list as there's so many fish I like, many of which are either too big, or too aggressive for a majority of what I'd like to keep. I'm also torn on whether this is too many fish or not, but I think it's a good mix of mostly peaceful fish that'll do well together.
Everything below is listed in order they will be introduced into the tank, and everything will be QT'd for a minimum of 6 weeks before being introduced into the tank.
Fish
1 x Wetmorella albofasciata (White Banded Possum Wrasse)
2 x Paracheilinus carpenteri (Carpenter Flasher Wrasse) M/F combo of course
3 x Sphaeramia nematoptera (Spotted Cardnalfish)
2 x Amphiprion ocellaris (Ocellaris Clownfish)
1 x Cryptocentrus cinctus (Yellow Watchman Goby)
1 x Chromis cyaneus (Blue Reef Chromis)
1 x Ctenochaetus strigosus (Kole Yellow Eye Tang)
1 x Gramma loreto (Royal Gamma Basslet)
1 x Pterosynchiropus splendidus (Red Mandarin) waiting at least 10 months after the cycle
1x Acanthurus japonicus (Powder Brown Tang) Adding last due to aggressiveness
I think your fish list is excellent, you will have room, biocapacity and copepods for a pair of red mandarins.
Inverts
2 x Thor amboinensis (Sexy Anemone Shrimp)
1 x Lysmata debelius (Blood Red Fire Shrimp)
1 x Lybia Tesselatta (Pom Pom Crab)
2 x Neopetrolisthes ohshimai (Porcelain Anemone Crab)
1 x Alpheus bellulus (Tiger Snapping Shrimp) will be added alongside the Goby, QT'd separately though
1 x Entacmaea quadricolor (Rose Bulb Anemone) waiting 1 year to afford better lights/mature tank
1 x Heteractis crispa (sebae Anemone)
You might consider a pair of alpheus soror pistol shrimp; they are non commensal but interesting and gorgeous
Clean Up Crew [not listed in order]
2 x Elysia crispate (Lettuce Sea Slug)
1 x Mespilia globulus (Blue Tuxedo Urchin) pretty but a bit of bulldozer with corals and rock structures. Urchins in general are like that
1 x Strombus alatus (Fighting Conch) I would increase this number to 3
5 x Nassarius sp. (Nassaarius Snail)
5 x Turbo fluctuosa (Turbo Snail)
5 x Cerithium sp. (Cerith Snail)
5 x Astraea phoebia (Spiny Star Astrea)
10 x Nerita sp. (Nerite Snail)
In general, VERY well thought out
