Can you mix different-sized gouramis in one tank?

A bit late to the discussion if you went over the weekend, and it's been years since I had any gourami but when I was young I tried a honey and a dwarf in a 35 gallon community tank with a few cherry barbs and neon tetras. The 2 harrassed each other non stop, not outight aggression like cichlids fighting, but always tattered fins and constant chasing. In restrospect the tank was probably overstocked, and poorly done, it was my first...

Actually some things came up and I couldn't go, but I do intend on going sometime soon.
