hard to read huh...nothing is easy if u wanna learn!
i dont know anything about animal protein actually ...and i dont really believe what i read anyway, unless i try it and see the result for myself. maybe there is some truth about animal fats..thats why discus breeders use only beef heart, well, i wouldnt know. in thailand they feed their fishes with live shrimps...and the female shrimps have eggs under their bellies, it was said and already proven thats those eggs will make the colouration of fishes brighter.the downside is if those fishes dont get a steady supply of shrimps ...they will lose their colouration after a week or two. well, it doesnt bother me anyhow...just as long my fishes are happy, they will exibit their colours naturally....pale or bright..its totally up to them and their mood...i wouldnt want to get mixed up with their fishy business
