I had a Dwarf flame gourami a long time ago in my first tank. He was fine for about a week and then went on a ravenous rampage I woke up to a half dead male guppy with no tail on the bottom. He was fine with the platys only because they could escape he ate the fry though. My experience with honey gourami's on the other hand has been wonderful ive kept them with otto cats corydoras and rummy nose tetras with no problem.
