How many fish can i have

[Matt7thompson]

I have a year old 30 gal cube reef tank and im not sure how many fish would be too much. I currently have 1 clownfish, blue damsel, algae blenny, firefish, and a yasha/candy pistol shrimp pair. I havent ever had problems with any of these guys and im thinking about adding a six line wrasse to add color and hopefully take care of these bristle worms. Is this a bad idea? I also have lots of hiding spots in my tank with the live rock. Any insight is appreciated, thank you.

I think that would cap off the tank pretty well.

A 6 line can become aggressive and will need a cover as they can jump
