Is there room for anymore fish?

I think I know the answer but wanted your opinions if there is more room for fish. I would like to add a black and white clown or pair if there is room I know they may not get along with my other clowns but had success before with my last tank and would love to see them together again.
I have a 150g tank with 55g sump.
My stocklist consists of
golden wrasse
yellow tang
blue hippo tang
flame angel
2-clowns not sure what kind
2-green chromis
fire goby
lawnmower blenny of some sort
scooter blenny
mandrin goby
yellow watchman goby with pistol shrimp
chiton goby
cleaner wrasse

INVERTS
5-6 peppermint shrimp
2-cleaner shrimp
1-fire shrimp
3-boxing pom pom crabs
6-8 emerald crab
3-different star fish serpant, brittle and dont know the third
1-pencil sea urchin
and of course many blue/red hermits many misc. snails

Missing critters dont know it there alive
second pistol shrimp
high fin goby
A male fairy wrasse cant remember exactly what one have not seen it since the day I put him in he was barrowed at the LFS and think that is what he is doing now but have not seen him at day or night hope he is still alive its been about month now

 

there should be room for more in a 150 gallon... maybe a midas blenny, a cleaner wrasse, Foxface?

 

I definatly would like a pair of black clowns and if there is room for anymore after that I am open for suggestions

 

I wouldn't add any more fish, it will give a weird "crowded look"
HTH

 

Well, couple of questions need to be answered first.

The first is if your filtration can handle the bioload? Quality skimmer, large fuge or carbon dosing?

The second is an observation of your current livestock. Is everyone healthy, with no sign of ich (which is usually induced by stress)? Is everyone playing well together? Probably the blue tang or the angel would be the first to show signs that the tank is too crowded.

The third is the behavior of your current clowns. Are they mated, and is something hosting them (aka, a favorite spot)? If so, likely another pair will have enought room to find their own spot.

 

I would not add another pair of clowns, it will most likely end in disaster.

+1 to about what type of filtration you have.

and +10 to 1.0Reef, I hope you have a huge pod population to take both a scooter blenny and mandarin. How long have they both been in the tank for?

 

I set up my tank in March on st patricks day of this year I bought a 125g established tank he had it for a year and a half and bought it from someone else so I would guess its been about 4 years old and used his setup for the 150g tank I rebuilt, liked the size better than the 125g aftler adding that tank it looked bare so I went to a fellow reefer who had a 75g tank that was established for about 15 years and bought all the contants it the tank. Then everytime I ordered something from reefs2go I would buy more pods about 4000 so far and in fact they had a daily special today with 2000 pods and refugium plants and then I added 2000 more just to keep them happy and fat. I dont think pods are an issue.
As far as the fish getting along they are doing great the clowns hang out together during the day but at night they go to there own anemone and everyone is healthy matter of fact when I first added the flame angel it broke out with ich and but cleared up in less than a week (thank god) only thing that fight are the chromis's they chace each other time to time

I will post pics of my filter system in a few min.

 

Here is my sump its 55g one half has about a 2-3 inch sand bed with some liverock and then chateo(I have some other veriaties coming soon from reefs2go) and its devided by a filter media then a SWC protien skimmer, phosban reator, return pump, grounding probe, and then on the outside of the sump is a lifeguard filter system that has a filter media followed by a carbon media and then a uv sterilizer.

 

This is an old pic of my tank I will post an updated one tomorrow but you can see how I created a shelf to give more room for swimming in the center of the tank. In this pic there are 2 fire fish but one disappeared a while back and now there is just one

 

why shouldn't cleaner wrasse's be in aquariums?
