I am planning on a community tank with some of these little gouramis, probably only one species of the three types. It will be very heavily planted and probably about 30 gallons. Are fish from the Danionella genus a possible tankmate? I am looking for tiny and unusual (or tiny and fluorescent green) tankmates. But not knowing these fish well I can see two ways this could go wrong. Either the gouramis might eat them or their sharp teeth might hurt the gouramis. Any thoughts?
