Hello. Im planning on getting some kuhli loaches, gouramis and guppies. How much should I feed them?? I really haven't been able to find an answer to this question. Some say as much as they can eat in 30 seconds, some say a pinch (how much is that anyway?), I've seen people fast their fish for one day a week aswell - is that recommended? Im planning on feeding flakes and bloodworms - but how much? Also - should I get sinking pellets for the loaches?
