Max fish count for a 120 gallon

[Fmellish]

I have just set up a 120 gallon reef tank, see my little red house link. All of my fish are babies, pretty small with my tang being the largest at about 2" long. I have a total of 7 fish including a green banded goby half the length of a toothpick that I'm surprised hasn't been eaten yet.

Here is the livestock I currently have.

3 Resplendent Anthia (1M / 2F) each 1.5"
1 Sixline wrasse 1"
1 Sailfin tang 2"
1 Percula clownfish 1"
1 Greenbanded goby .75"

So I'm wondering, for my 120 gallon 4'x2'x2', (nice and wide), can I add more? Assuming the tang gets to 6" and the rest maybe an inch or two bigger each, do I have room? I see some people stick a ton of fish in a tank, and I don't want to be one of those people. I get asked all the time what my next fish will be. Apparently my tank looks kinda fishless to most people.

What do you all think? SHould I go for one or two more fish? And what would be compatible with what I have?

UPDATE:
In this image below you can see all of my fish except for the greenbanded goby. They are all together on one side of the tank in this pic.

Thanks

that sailfin grows to 15" in the wild. i have one that i bought 1.5 years ago and it is growing very slowly. it is only five inches now.
i think when all those fish grow you might be close to capacity. do you have a sump and how large is it?
i like small angels like the flame or coral beauty. A hawkfish would work also but the flame angel will add a lot of color.

I have a 30 gallon sump running about 20 gallons of water, so probably 140 gallons total capacity. I also have over 200 lbs of live rock, so lots of filtration.

And the tank is wide and deep so there is lots of swimming in thre dimensions. Its not like most tanks where the fish can only swim from left to right and then have to turn around. My fish can swim from front to back with lots of room also.

I've tried to set up a habitat that is totally stress free, and I wouldn't want to change that by adding another fish.

The flame angel is beautiful though.

15" ?? If my tang gets 15 " I'll have to take him back to the LFS. Keeping a 15" fish in 4'x2' box seems kinda cruel.

I think you have a good mix already. I like to go with a light bioload and concentrate on the corals, but you have room for more fish IMO.

when i first set up my 125, I was gung ho about loading it up with fish and corals to make it a very busy tank. i have learned over time that a light bio load is important in keeping most corals healthy and growing. i have the 5"sailfin, a 5"kole tang, a 2 1/2" flame angel and a 2" flame hawkfish. it took about 3 months after a 4"voltans lionfish and a foxface surgeonfish died and i returned to my lfs 2 yellow tail damsels before my nitrates went down to 0 and phosphates are less than .1 mg/liter. now all my hair algae is gone and my corals are growing like crazy. i have a toadstool coral in the middle of the tank that almost touches the front and back of the tank.

i think that you should get another clownfish

I think its safe to say the Sailfin will outgrow the tank in a few years - might have been better off with a Yellow, Kole or Hippo tang instead...

But overall, I'd say you have room for 2 or 3 more smallish fish.

A Flame Angel would look fantastic, and another clown to make a pair would be nice...

I think you have the makings and the attitude for a very nice tank...

Thanks everyone. I really think the Kole tang looks neat. I may get one of those when it's time to let my Sailfin move on to a bigger tank. Although taking him back to the LFS doesn't ensure he'll get a bigger tank. The LFS may sell him to someone with a 50 gallon. I've seen people put lots of large tangs in small tanks. Small meaning 90 gallon or less.

The hippo, (blue), tang is pretty; who can dislike such a nice blue color. However I see so many hippo tangs acting unhappy in their tanks, either always hiding, or with HLLE, so it appears to me that the common hippo is too much of a high maintenance tang. I may be wrong, but I've never seen a happy one.

Another clown would be nice. I used to have two, but one died.

Thanks

I have 12 large fish in my 180. I skim hard and feed hard too. I like to use 2 skimmers that are different brands so that my "Skim net" is wide and gets everything. I am planning to add 3 fire fish soon. My fish list includes a 5 inch orange shoulder tang, 3" hippo, 4" valmanagi tang, 3 green chromis 1 is 1" 2 are very small, a 2" dusky jawfish, 2 2" yellow tangs, a 4" orange anthias, a Clarke clown and a damsel which I need to remove. I am going to add ozone soon which will help with the bioload. I am able to keep all of these fish and have healthy sps and lps coral
