Can I Add Another Pair Of Gourami?

[Justpeachy]

right now in my 55 gallon tank i have
2 farowella,
1 upside down cat,
4 cory,
2 balloon molly,
3 platy
6 neon tetra,
2 weather loach,
2 fancy guppy,
3 skirt tetra,
2 blue gourami,
and 2 big snails.

i wanted to find some type of gourami that would get along with the blues, and also stay small,
but at the same time, i think my tank might be full??

any advice?

not sure if it helps, but i filter with a fluval 305.

thanks.

Maybe the honey gourami. How small?
