Looking to add fish and/or coral, need advice

[HumanIMDB]

We're looking to add a fish or two and some new corals to our 10 gal nano and are looking for advice.

For coral we currently have:
Green Frogspawn
Green Ricordia
Blue Mushroom
Brown and Green Zoos
Green Blastomussa Wellsi
Waving Xenia

For fish we currently have:
Green Clown Goby
Blue Hermit Crab
Emerald Mithrax Crab
Various Snails

Our setup is:
Coralife Aqualight 96w Quad 50/50
AquaClear Power Filter modified to hold Chaetomorphia with light
AquaClear 20 Power Head
Fluval 104 with Carbon and Live Rock
Tronic 50w Heater

We aren't looking to much but we want to add something.

We would like some more colour diversity as well as some diversity in activity. (i.e. our goby is nice but we would like something that swims around a bit more.)

We used to have a pair of True Perc Clown but they managed to escape, one after we installed an egg crate cover. We may give them another chance, but probably not.

The only fish we've looked at that our research tells us is compatible with our system is a firefish, but we're concerned that it will just escape too.

Any ideas/advice you can give would be greatly appreciated.

Thanks,
Chris

I would look into some more LPS. You can get some nice trumpet, candy cane in there. If you have the room, open brains are nice. I have/love the red ones!

I would not go for the firefish due to the fact that they are jumpers. If you have a top on it, then it would be okay. But if your open...no way. You may want to look into getting a blenny of some sort. Tail spots are nice and they stay small. IMO, i'd try a clown again.....
