Room for two more fish

[Breakthecycle2]

Well, the dreaded happened yesterday in one of my 40g. I woke up to find not only my Dracula Goby, but my newly purchased awesome looking blue dot jawfish fried up on the floor. Somehow (as usual) they got out with a lid on. I am thinking of this jawfish (dont seem to be jumpers) Drs. Foster and Smith Diver's Den® - Opistognathus variabilis

and id like a wrasse (hooded?). Just want your opinions!

Current stock in this tank:

pair of Goldflake Maroon clowns
Lubock wrasse
multicolored angel
Fridmani Dottyback.

The jawfish should be fine but I wouldn't add another wrasse due to the possibility of aggression.

Any of the jawfish I've kept wound up on the floor. They look for the tiniest holes and aim for them to escape. I've kept multiple fairy wrasses in tanks and they seemed to hang together like buddies. I did add them together though. I'm not sure if that makes a difference or not.
How large are those clowns? I would be more worried about aggression out of them in such a small tank than anything else.
