fish that is kept well in groups??

I have a 55g reef set up. Currently have a tribal blenny,pink spotted watchman,chromis, foxface and two clowns. The blenny stays on his rock all day and watchman hangs out under rock with pistol. So only movement I got is two clowns chromis and fox. Seems like none of them are big swimmers and hang out in one area of the tank.. what's a good fish or group of fish to add for some more movement to the tank?? Any suggestions?

 

green chromis..very active and can be kept in groups ...small playful fish..

 

yellow tang also...very active...reef safe

 

Heard green chromis are not kept well unless they are in 8 or more I started with 3 they all picked on each other now I have one left lol

 

i wouldn't put one yellow tang in a 55 much less a group.

 

Thought about tangs .. but with a fox face already in the mix didn't want to much yellow

 

??? I've seen them in much smaller..

 

Well I didn't a little browsing about the Tangs found anything from 30+ to 55g all the way up to 100g minimum .. strange.

 

Green chromis are your best bet in the size tank you have. But they do have a pecking order that can be pretty brutal. Tangs are really not an option. I would look into some smaller fairy and flasher wrasse species. They are great open swimmers and very active.

 

Fire fish are a good schooling option w/ lots of color and movement.
