I’m gonna go over each individual fish:
Clown pair- Great.
Yellow Watchman Goby- Great. Its natural symbiotic relationship is with the Tiger Pistol Shrimp, but can also work with a Randall’s Pistol Shrimp. Randall’s is smaller.
Black Cap Basslet- Great.
Yellow Assessor- Great, but not sure if will get along with the Black Cap. I’d ask.
Flasher Wrasse- Great. Any of them would go into a 75 just fine as they top out at 3-3.5”.
Fairy Wrasse- Great. Many to choose from.
Yellow Eye Kole Tang- A 4ft 75 is the absolute minimum I’d keep a Tang in, and many people do keep the smaller Bristletooth Tangs in 75 gallon tanks. I’d personally be more comfortable putting a Tang, even a Bristletooth, in a 90 (with more width than height), but if it’s your largest fish then it should be fine. An alternative would be the Tomini Tang.
Flame Angel- Great.
One Spot Foxface- Could be OK for a while, but will have to be rehomed.
Ignitus Anthias- These remain small. How many do you plan to have? I’m not sure if they kill each other off like other more aggressive species. I’d ask.
Fathead Sunburst Anthias- Beautiful species. Not sure how it would get along with the Ignitus but shouldn’t be too bad.
Firefish- Add before any aggressive fish, these are extremely timid, IMO almost too timid for many tanks. The Helfrichi, Purple look better than the standard red ones IMO. An alternative would be maybe a pair of Zebra Dartfish.
You’ll need a cover for your tank, preferably with no gaps.
