How many fish in a 120 Gallon?

I think I might have too many fish in a 120 gallon and wanted to know what you all thought. I have:

1 Naso Tang
1 Unicorn Tang
1 Blue Tang
1 Yellow Tang
1 Vlamingi Tang
1 Large Regal Angel
1 Diamond Goby
4 Green Chromis
1 Diamond Goby
1 Six-Line Wrasse
1 Perc. Clown

Is this too many fish?
 
Probably too many... I definitely would add anymore. If you have a very good skimmer and you are religious about water changes you can get away with it, but as those tangs develop, grow, and mature they will not only produce a lot of waste, but they will probably hate eachother. If you are considering downsizing, I would suggest finding a new home for the Unicorn or the Baso, both fish eventually reach 2 feet + in length and they grow fast.

Just my 2 cents...
 
Just with the 5 tangs is a huge bioload.....If you insist in keeping them youll obviously need a good skimmer, and weekly water changes.

Then again u have some of the bigest species of tangs all 12 inches plus when full grown....
 
:) Thanks for the help guys. I'm getting rid of the unicorn tang which is the biggest right now. All the other tangs are less than 3". It's hard when you're gone and your parents go to the fish store and don't listen to your advice, haha.
 
if u wanna get rid of any of the tangs, let me know..i just finished a 180 gallon and need to stock up.
 
see how your nitrates are and then that may be a hint to, on how many fish you can have. If you nitrates are high all the time, then you have too many fish. Keep in mind that if you have to many fish the tangs may be stressed as well and they can easily get ich. :D
