Pick a fish for my 55

I've got a 55 that i just upgraded to that is stocked with;
1-Flame Angel
1-Blenny
2-Clowns
1-Shrimp Goby w Pistol shrimp
1-Sixline Wrasse

Some of you may have seen my thread about the Magenta Dotty i added but unfortunatly my Sixline didn't approve and he's gone:-X.
I would really like to add another 2 fish and would like some suggestions.I've got about 60lbs of L/R along with a 65gallon rated skimmer and a hang-on just for some added flow/clean-up.

I am a believer in letting the L/R be my filtration along with a good skimmer.
My tank has been up for about 7 months and also contains the following corals:
Frogspawn
Pipe Organ
Cabbage leather
Toadstool
Dendro
Zo's
Schrooms

I'd love a Bangaii but never had luck with them before. Heard they have ORA Bangaii's but haven't seen them in N.J.
Not really into the Royal Gramma or Chromis.
I'm interested in hearing your opinions.

 

That is pretty close to maxxed out at the fishes adult size and especially with the skimmer. Skimmer ratings are usually for light loads and you are pushing heavy. That skimmer is probably good for 40 gallons heavy load.

 

I believe the rock along with the skimmer will be acceptable. I also do weekly water changes of about 15 gallons.

 

If you wish to try get something in the 3 to 5 inch range as an adult. Your sixline is most likely going to make it rough on any newcomer.

 

1 more small fish only must be small though..

 

Maybe a neon or sharknose goby (is a cleaner species).

 

Scarlet Hawk, Firefish

 

I like orange spotted gobies. They grow to 3"

 

You aren't considering the psychological effects of overcrowding on the fish, and the disease outbreaks that will follow from stress....

 

You will like the look and character of a bicolored blenny. I would say that or a lawnmower blenny.
