fish stocking questions

[langley reefer]

Will be upgrading my tank early in the new year and wanted to get some advice and experiences from some fellow canreefers. Was pretty much set with what I was going put in the new tank until my sixline jumped to her death last night. Losing the sixline opens up many options.

I currently have just two chromis and a very mellow ocellaris clown. Looking to only add small peaceful fish.

I am definately getting a tail spot blenny. Would like to add a high fin goby. Does anyone have experiences housing these two together?

I also want another wrasse, preferably one that stays small, is reef safe and not aggresive. Anyone have suggestions or opinions?

And lastly I would like to add some mid swimmer that can Contrast the blue/green chromis.
Cardinals, firefish?

I have done alot of research but value the real experiences, suggestions and opinions of you guys more.
