lol, as said, this is perfectly normal. i kept two gouramis in with about 20 molly fry once. the day came to remove the molly fry to take to the lfs for trade in. as i was netting them all up, my gourami must have decided i looked like a tasty treat, he spit at me and hit me right in the eye!!!!! (either that or he was upset i was taking away all his little buddies). i was laughing so hard i had to take a break from getting out the fry. i knew they did that, just never expected to witness it in my tank.
