all the cool kids in my tank are usually playing final fantasy something or another. must be a generation thing. the only fish that seem to refuse this is my paradise fish, didn't realize tub raised fish would be so prissy. their like "sir,that is neither a crisp nor raw prawn." one of things i did find out is fish like my angel, (you know fish that stare at food forever before striking?) take few feedings before they figure out how to attack. i'd like to note a behavioral change in my blackspot barb since feeding this food, he has been very aggressive to the females, to the point where i had to put him in time out for two weeks. since feeding this food his aggression towards the females has been reduced. he'll still give them a normal barb chase then stop, maybe grab a bite from the cube. i think the food's constant presence means one less stresser for him and provides a distraction. also he is in full blown breeding garb, chin and snout all rosy filaments at full mast, so he should be more aggressive.
