I now have 4 of these guys in my 20 gallon planted tank, they clean the algae off the walls and plants, and school together around the tank- which is odd? They show no aggression even though all 4 are males, and are just beautiful, lively, hardy and curious little fish! I highly recommend them!
I've got eight of these floating about somewhere in my tank. They are the "golden" colour morph - not pictured here - and are very attractive, although I prefer the wild colours (they're just difficult to find here). They're rather tougher than dwarf gouramis (lalia) but as has already been said, do have a fondness for certain plants. It's only in quite large number that they can do very much, though. Youngsters or newcomers are easiest to feed by crumbling spirulina flakes so they become trapped in dense foliage where they hang out. They'll pick their way through it eventually. Afterwards, they will accept most things, but ensure you feed spirulina flakes or other vegetable matter occasionally. Very, very shy fish when young. Keep in decent numbers in a decent sized tank, and provide lots and lots of plants for cover and food (otherwise, you'll never see them). They will show aggression eventually, but with enough cover they won't come to any harm.
I have 2 honey gourami in my 5gal planted tank, with 4 RCS. Mine are more gold with red on the tail. I haven't seen them bother the shrimp at all, but I'm not sure if they would bother baby shrimp yet, we'll just have to wait and see. I haven't had a problem with them eating any of my plants, most of the time they follow each other around the tank and generally stay close to the surface, or pick at the rocks and driftwood.
