Can i add more fish?

I have a 29 Gallon Biocube and i would like to add a few more fish and or coral because my tank to me looks so bare.

My Fish:
1 Ocellaris Clown fish
1 Six Line Wrasse
1 Yellow Tang
1 Sleeper Banded Goby

My Corals:
1 Cup Coral
1 Toadstool Mushroom Leather Coral
1 Hard Tube Coco Worm
Small amount of Button Polyp's
1 Chili Coral

I am trying to mock the Florida Reef's Please Help!! I added a few pictures Below....

 

Beautiful tank. Your tang will out grow your tank very shortly. They need a tank that is a minimum of 4 feet long just to have a chance to keep them healthy over the long haul. I would say you are at your fish stocking limit until you find the tang a new home. Corals you can definitely add.

 

We have had that tang for 3 years and it has not gotten any bigger than that and was in a 24 gallon biocube but and he is about 4 now and has not grow since.

Do you know any good coral i can add i like coral that will spread over time and cover a whole area.;D

 

ya i agree get rid of the tang and maybe you can add one more fish but you can definatley add more corals

 

that would be mushrooms zoanthids and yellow polyps

 

oooooo those sound cool ;D;D;D;D I love the ocean and corals xD i <3 Microorganisms to ...

 

Star polyps and daisy polyps like to spread and cover a lot of area. Zoanthids and button polyps can do the same. LPS corals like chalices spread. Encrusting species of SPS would work for the top of your scape.

 

What do u mean?? Like encouraging them to grow and spread? and the top of my scape must be the top top rock

 

If you get rid of the Tang you can def put something else in there. I'm suprised yours hasn't grown in 4 years. I have had a blue hippo and he has grown a lot in just 2 months. Tangs love to swim and need lots of room to do so.

Think of it this way, a human being can survive in a closet with food & water, but doesn't mean they'll stay happy & healthy in there.

 

Some species of montipora grow covering the rock just like GSP and polyps. Yes on the top top rocks.
