Are There Any Larger Fish That I Can Keep With A Dwarf Gourami?

[RockyRaccoon]

By large fish I mean 2inches or longer. I have a 20 gallon long tank stocked with 1 dwarf gourami, 6 pristella tetras, and 6 cories. any ideas?

bristlenose plec ?

thanks, but i've never been a plec fan. im hopin for somethin that'll be a little more active. i was thinkin another dwarf gourami would be cool but I don't want to deal with the aggression that might cause stress... and no pet stores around me have females. any other ideas?
