Looking to add new fish

I have a 150 gal saltwater live rock tank and lost two of my fish about a month ago when I went on vacation. (I wish I could find someone who really knew about aquariums when I go out of town). I want to add some fish to my tank and am looking for some advice. I have a fairly aggressive tank with medium size fish 5"' to 7"'. I currently have a porcupine puffer (my favorite) , a lunare wrasse, a regal blue tang, a yellow tang, a tomato clown, a large hermit crab and a really cute striped kuhli loach.

I would love to add more yellow tangs for the color, but am afraid of their territorial preferences. In the past I have minimized the territorial problems by rearranging the live rock just before I add new fish. It seems to disrupt their "home base". I have not been sucessful with lions over any kind of reasonable time periods.

Anyway, any suggestions would be appreciated.

150 gal. rectang. 48" X 24" x 36" high; reservoir filtration; Eurofil 125; 2 - Magdrive 950 water pumps; 200W heater; protein skimmer; ultraviolet sterilizer; 3 sets of power compact 96W lights

 

i would stay away from more yellow tangs i have had nothing but negative expierence 2 or more are added to the same tank. how about a naso tang

 

Thanks. I tried a Naso tang and had trouble getting him to eat. He died about two months after I put him in.

What about other clowns or wrasses? How large do I need to get my new fish with the other fish being so large?

Lunare Wrasse - 7"
Porcupine puffer - 5"
Regal tang - 6"
Yellow tang - 5"
Tomato clown - 4"

 

+1 on the triggers. A Naso would be too docile IMO. They are really peaceful fish, and that could be a lot of the reason why you didnt have luck with your last one.
I would just make sure to get something that isn't too small

 

Thanks, I will look into different varieties of trigger. I am not familiar with the miniatus grouper. One of the first fish I had was a panther grouper. He was wonderful except he never stopped growing. At 8" and growing I had to return him to my LFS. What is the size fo the miniatus grouper? Will it keep growing forever?

 

What about a lionfish? Their really cool

 

I like wrasses. very active most of th etime and exremely colourful. I like the mystery wrasse, but you'll be droppin a bit of coin for that baby.
