two perculas need a new mate

[105man]

I have two perculas in a fish-only 20 gallon tank, that have cohabited together a long time. Id be interested in suggestions for another fish or two for the tank.

Thanks.

I have 2 percula's myself.

In my tank, I also have the following:

1 Coral Beauty (totally oblivious to the clown's presence)
2 Bangai Cardinals (also unaware)
1 Beau Gregory (little aggressive, but does no harm)
1 Fire Goby (seems to like the clowns...and a beautiful fish)
1 Clown Goby (too busy hiding all the time to give a dang)

so any of those will work.

Clowns tend to get along with most fish, except certain other clowns that are added later.
