Want to add another pair of Clowns

[FishyBiz]

Hey guys
Im thinking of adding another pair of clowns to my tank and wanted to get some feedback.
I have a 190 gallon SPS dominated tank and have had a pair of true percs for about 3 years. They have only been in this tank for like 7 months. In my old tank they used to hang out in their nem all day and all night and showed virtually no signs of aggression. There are no anemones in my new tank and the clowns swim from side to side with no sings of having an actual territory.
I was thinking of adding a pair of onxy or all black but what do you guys think? Same size? Bigger? Smaller?

How big are they?

They should also be fine because Pers are mainly a peacful clown and seldom show any aggression toward other clowns.

So in my opinion they should be fine, but definatly not smaller same size.

My true perculas killed a couple of new perculas that I put in my 200 gallon....not just bit fins, but killed them. Lesley
