Well,i need to find out some special feeding requirements for my fish before i purchasing them.Hoping that i can provide them what they need.I think not only the quality and the kinds of food affect the sizes and health of the fish,but also the amounts you feed them.Yeah,in any case,we need to get our fish to eat as many different kinds food as we can to ensure they are getting everthing they need.Some fish are used to eating all the time,so you have to feed them as often as is pratical(small amouts at least once per day).But for others,they can survive without several days at all.If you want your fish grow faster and bigger,then watch out the amouts you feed them.In a word,the more you feed your fish the faster they will grow to their maximum sizes.
