90 gallon marineland tank w/approximately 80lb of sand (aragonite) - Tank is FOWLR. I have a 30 gallon sump with a refugium, I have not set the refugium up yet but will be doing so in the next 3-4 weeks (currently just live rock rubble in it and a light that I hope is powerful enough for algae growth

)
Current fish/inverts:
3x Tank bred Ocellaris Clownfish (guy at the store told me to get three-five, instinct said get two but I listened to the LFS guy for some stupid reason... Afterwards, people on here have said to "worry about the third" once two of them pair up, but two other LFS's I stopped at yesterday said that the 3rd will be fine since I got them all at the same time and basically that the female will become a "group leader" and have a "love triangle" going, they said if it was a more aggressive clown species the third would indeed be "screwed"... Considering the wide-variety of responses I've received and the fact that the LFS I purchased from has a "no returns on livestock policy", I've decided to just keep an eye on them and pull out the 3rd if he begins to get bullied once two of them pair - If you have any suggestions/advice I'd appreciate it)
Three clownfish never work long term. Once sexually differentiated, the female will kill the third one or cause it to jump. My advice is not to listen to those LFS as they do not know what they are doing. I would especially NEVER purchase from the initial LFS that sold them to you.
1x Cleaner Shrimp
3x Turbo Snails
6x Nassairus Snails
3x Bumblebee Snails (are these guys evil? See next purchase...)
1x Trochus Snails (had three but two were eaten by the bumblebees...?)
5x Astrea Snails
6x Hermit Crabs (3 red legged, 3 blue legged)
hermit crabs will kill snails for their shells
Intended future purchases:
1x Fox Face Rabbit Fish (Some say 4 feet is enough room, others say 6 feet so if I see he's stressed out in the 90 gallon once he reaches maturity, I will swap him out for another small one - I *really* would like this fish but if you think it's a horrible idea I will listen)
The minimum tank size recommended is 125 gallons; Reef Central does not recommend swapping fish out but rather purchasing for the tank size you have now
1-2x Heniochus (for my girlfriend)
The minimum tank size recommended is 125 gallons; Reef Central does not recommend swapping fish out but rather purchasing for the tank size you have now
1x Diamond Goby OR Blue Cleaner Goby (I honestly don't know which would be better?)
Both are fine, the cleaner goby would have interesting behaviors but so with the diamond goby if paired with an alpheus randall shrimp
1x Mimic Tang
two large grazers in this sized tank is not recommended but the mimic tang is preferred to the Foxface.
1x Flame Angel
1x Green Mandarin Dragonet (6-12 months down the road, also he's a *maybe*)
BTW - Any order in which to purchase these next fish if you think I'd be okay with them?
Thank you!!!
