One or Two more fish

My 29G BioCube has been up and running since April. I have 2 clowns and a Scooter Blenney. I am looking to add one or two more fish, any suggestions.

 

Royal Gramma or firefish, but any fish may have a hard time with established clown fish in the tank.

 

So you are saying once you put clown fish into a tank you can never put any other fish in there?

 

Of coarse you can,but the clown can be very aggressive until eveybody settles in and learns their pecking order.I have a 6 line wrasse and a firefish,both are awesome!

 

I agree with the above. One way to lower the aggression would be to re space your rock before you add the new fish. This will confuse the clown, thus giving all fishes a chance to establish a new home.
