OK perfect I think the whitemouth will be the choice. Now I have a few more questions before prepping. What is the rate of growth for them per year say? Should I get super small or can I get a larger one right off the bat as a show peice? Any tips or tricks to keeping them besides the recomended lid I see everywhere? And here is the tankmate list what order would you think is best?
eel
picasso or niger trigger or maybe both
puffer
larger blonde naso tang
I would get the largest one you can find, but they grow pretty fast when they're small if you feed to satiation regularly (1-2x per week). Once they get to ~24" (only takes 4 months or so) they slow down.
No real tips to keeping them aside from making sure they stay in the tank/out of the overflow. Very hardy fish. Mine has survived an accidental tank nuke that wiped out the coral and killed all but the eels and a trigger (that I still have), months of neglect, 9 months of voluntary starvation and a few times on the carpet and has never looked the worse for it.
Just FYI you can easily keep corals with eels; it's just the soft arthropods and sometimes clams that are at risk. I kept a "predator reef" for a long time with a whitemouth moray, goldentail moray, Hawaiian black durgeon trigger and Caribbean scorpionfish. It was absolutely gorgeous and I'm trying to re-build something similar atm.
As far as triggerfish, get whatever species you like that will tolerate tankmates in the long run (i.e. no clowns/queens/undies - when adults, these kill everything or die trying). My black durgeon (
Melichthys niger, NOT the regular
Odontus niger) has been a very nice and active addition. The
Xanthichthys species are attractive too. The
Xanthichthys can be kept in pairs; in a tank that size I don't know that I'd try 2 unrelated trigger species.
As far as puffers go, most of the neat ones will outgrow your tank. I'm a big fan of
Arothron meleagris and
A. stellatus though.
At full size you're already pretty close to your maximum bio-load with that group, and most things big enough to survive that tank would push you over. You might get away with a scorpionfish or maybe a few damsels that you replace every month or so.
