Restocking 180gallon tank

I'm considering restocking my tank and wanted to solicit opinions. I presently have the following:

- Harlequin Tusk (4.5")
- 6 line wrasse (3")
- Blue Tang (4.5")
- Maroon clown (4.5")
- Blue Throat Trigger (4.5")
- Coral Beauty (3.5")
- Swallowtail Angel (3.5")
- Black Dominoe (1.5")
- 4 stripe damsel (1.5")

I'd like a tank with 2 of each species and fish that can grow to at least 4-5" and add some color to the tank, while being moderate to easy to care for (I tend to travel frequently). Was thinking of ditching both angels and go for juvenile emperor and a queen angel. Then, would like to add a Bannerfish and maybe a Racoon. I'm open to suggestions of another colorful Tang and any other interesting fish that meets above criteria.

 

Well, If your looking for a tang, the Naso Blonde Tang is pretty easy to care for and will fit in nicely in your 180 gallon aquarium. Has alot of color to it! The only con is that it grows to about 1'6", so I don't know how your current stock is fitting in, but if you have extra room, consider this.

 

Scratch that, sorry lol, but the Bristletooth Tomini Tang would probably be a better choice for your stock. Sorry, but I forgot to look at the current sizes of your fish! This fish can grow to about 6", which would fit in nicely with some color. ;D
