i purchased my gouramis from a private party and have them about 5 weeks. healthiest fish ever! I was dubious about buying from someone rather than a store. I did not know her but the price was right and they are very healthy. After i got them I started some investigation as to their temperment. After what I read I expected them to kiss/kill each other and then the rest of the tank mates (2 rosy barbs, three hi fin red tetra, 2 silver fin tetra and one golden sailfin molly (her mate died). I have seen the three of the gourami get testy and challenge each other but seems they have decided the pecking order. Only time they pester each other seems to be at feeding time. i am feeding dried flakes and dried brine shrimp 2 times daily. Am I underfeeding? Hope they won't be too hard on the moss.
