gg eat all, fake pellets, real pellets, thermometers, shrimp, smelt, fish fillet. i haven't seen a type of food my gourami doesn't taste. agression is sort of an issue. it punks everything and grows the fastest. smaller fish will get picked off an possibly killed. gouramis show no fear! lol. i do like my gourami the most right now out of all my fish besides my aros. they have great personalities
