What to add?

[Mr Sh0tgun]

I have a 24g tank with three fish: a bicolor blenny, a sixline wrasse and a wheeler's watchman goby. I want to add one more fish, but I'm not sure what. I want a fish that swims freely and doesn't perch like a blenny or goby. I haven't had much luck with clowns (killed two) and I don't wanna try another. So, I'd like to hear what fish others have/had that are not too agressive and would make a good "focus" fish in my tank.

I would be worried about adding anything because of the wrasse. Maybe a damsel would be nice. It could hold its on against the wrasse and I wouldn't think it would attack the others.

[Mr Sh0tgun]

I haven't had much trouble with my wrasse; they seem to be hit or miss. The wrasse actually swims around with the blenny and "kisses" it's gills.

I was thinking about adding a damsel, but the only one I'd want to add is a two spot domino, and from what I hear they're very agressive.

Anyone else have suggestions?
