I have this male dwarf gourami who isn't very scared of me. When i put my hand (just the fingers)in for a bit he came up and let me stroke his side once before he swam off. Now he lets me pet him fairly often and he's not that scared of me. Can you actually tame these guys? i know some large goldfish and cichlids can become very friendly, but I never heard of gouramis being that tame.
