Famale Opaline?

[phantomlink]

I have an opaline gourami and I'm trying to figure out if its a female or male before I move a tank around and possibly place it in my 75 gallon with 3 pearls ( 2 female, 1 male )
 

 
Right now it's living in a 20 gallon with some corys and kuhlis and baby upsidedown catfish, but I want to turn it into a 20 gallon long and keep it cory/kuhli related.  I think its a female but wanted to double check

Positively a female.

Nice, so there should be ( I know they're all different ) no problems if I put her in a larger tank with the pearls?

You should be okay.  I keep a large female Opaline with a pair of large Pearl G's, a female Paradise Fish, Glass Cats & Cherry Barbs.  Strangely enough the aggression in the tank is minimal.  I think it kinda works like a Cichlid tank in that having more sometimes is better because a bully can't center all their attention on a single fish.
