The Beginning of my first 125 gallon reef

[Reefing Newbie]

Hello everyone, as many of you may know by now, I have aqquired a 125 complete reef set up. After 3 or so weeks I am now starting to get my livestock plans in order to start with! Last week I purchased a juvinile pair of True Percs(they swim like dolphins lol up and down, up and down). They have started their second week of QT and no problems yet so I am hopeful that they are clean. Today I went to pick up a mix of snails(10 total) I think I got 5 cerinths and 5 nassuris(sorry for spelling) I know I need way more, but I didn't want to get 50 only to have 10 next week because of hermits, removing them as I see them lol. I also got 3 peppermint shrimp as they were 3 for 18, I have some small aipastia showing up. Okay now for my stocking plans. I would love to hear some thoughts on it, incompatiblities, overstocked...

2 True Percs
1 Tribal Blenny
1 Blue Eye Tang
1 Powder Blue Tang
1 Diagonal Bar Prawn Goby or Randall's Goby(Recommendation wanted as I can't decide lol, will have pistol)
1 Springeri Pseudochromis
1 Purple Firefish
3 McCosker's Flasher Wrasse(1 male 2 female)
1 Yellow Coris Wrasse

Not sure if I have room, I was wondering if a Green Mandarin Dragonet(will be last fish before the tangs) and a resplendant anthias or pajama cardinal would work? For the later two I was trying to get another fish that would swim out in the water column rather than hover in its territory all day like clowns per say. If both of the last two stay within a territory I would love to get suggestions on it! Also would like some help on what order I should introduce them in, clowns are going in first. I was thinking Flasher Wrasse's next?
