Which other Fish?

I have a problem figuring this out in my head. What other fish to add in a while to my 30g tank. I currently have a 6 line wrasse, 1 blue green chromis, and 1 randal goby. I lost 2 chromis and have just that one left right now. In the past i had a royal gramma which is a cool fish that I would add again, but wouldnt mind looking into other options. Ive considered a jaw fish bc i have a dsb. I really would like to have a perc clown, but have seen that there could be a risk when mixed with the 6 line. Is that true? I have seen them mixed b4 but seeing that chart worried me. What other fish should i look into?
They have to be reef safe as i have corals/polyps too.

Thanks!

 

Neon Goby, nemo, some dotty backs, blennies

 

When you say nemo you mean perc clownfish right? Sorry if this is a dumb question lol

 

and/or the false perc. clown, just be careful not to get the Yellow stripe maroon clown fish, they are very aggressive.

 

Thanks Lunatik! Yeah i had a maroon Clown one time. It was very aggressive.

THanks again!

 

Anytime my fellow reefer. Luna
