What fish?

the wrasse will eat shrimp.. any tang is reefsafe.
the salifin and naso get pretty big. cant remember extact size but its more than 10 inches. for both

 

You could get a reef safe angelfish! Gorgeous creatures. These ones are okay for 100 gallons and reef safe Angelfish for Sale: Saltwater Angelfish for the Home Aquarium

There are more, just not on that site. Google!

 

Thanks for the suggestions. As far as the angelfish are concerned - we've had 3 coral beauties die on us

 

I also am a fan of these but could never keep them as my tank isn't big enough and/or they aren't reef safe or safe for me to touch (lionfish):

panthers are sweet fish but they need such big tanks, 300g yikes!

 

They are beautiful when small but grow quickly.My LFS once had a two footer that someone brought in and it wasn't very nice looking and would make a mess of a 90 gal. tank.

 

My suggestions for the 90g-

Chevron Tang - Ctenochaetus Hawaiiensis
Chevron Tang

Purple Tang - Zebrasoma Xanthurum
Saltwater Aquarium Fish for Marine Aquariums: Purple Tang

Magnificent Foxface - Siganus Magnificus
Saltwater Aquarium Fish for Marine Aquariums: Magnificent Foxface

Chevrons are a little touchy till you get them eating prepared food. Purples once eating and get established are pretty hardy! and Foxfaces are Bullet Proof seems to be! Be forwarned that foxface's spines are venomous!

 

Thanks for the responses - I appreciate it.

Question: When a description of a fish says that it's compatable with reef aquariums "with caution", what does that mean exactly - will they eat the corals?

 

It means they may eat coral, they may not. Also means they may eat clams, shrimp, other inverts, etc.

 

def, I just put it on my list cause I want one, but def a no-no for a 90g
