None of the "rasbora" species are active, all are peaceful and fairly sedate. They thus make ideal tankmates to gourami. Just avoid the "dwarf" species that would almost certainly be eaten by any gourami as large as the Pearl.
And a 55g hex is ideal for gourami.
A group of pearl gourami, being one male and 3 females, would be good. Two males and 4-5 females would be the next step up, and while this certainly might work, it also might not, depending upon the behaviour of the individual males. All gourami males are territorial, much like all cichlids (one reason the two should never be together) and they usually consider the tank as "theirs" and will defend it against rivals. The profile (click the shaded name) explains more.
Other gourami is sometimes possible, but more with the smaller species (there are several inour profiles with photos) and none of these should be combined with the "larger" species like the Pearl.
Lots of plants, branches vertical, and definitely floating plants which are a must for all gourami. Have a look at the various rasbora in the profiles (under Cyprinids). Some of the quieter tetra (Characins) will also work, unless you want to be authentic with a SE Asian habitat, since characins come from South America (or Africa).
Pictus Catfish I would not. They need a group, they get large, they will eat smaller fish, they need more space...check the profile.
Loaches can work though, at least some of them. The kuhlii was mentioned, but if you want to go with fish that will be out and about more naturally, have a look at the Botia species (also under the Cyprinids). Botia kubotai and Botia striata come to mind, as do the two dwarf species in our profiles. Always in a group, 5 or more, as loaches are highly social fish.
Hope this helps a bit.
