Nowadays I am feeding my young guppies and swordtails with baby brine shrimp. I have learned that there is no other better food than baby brine shrimps for baby fishes, especially for the first two weeks from their birth. Their high protein content makes young fishes grow faster. I think the fishes really love the taste of brine shrimps because whenever I feed my fishes with baby brine shrimps they go crazy after it. So I have understood that baby brine shrimp is the best and safe food for young fishes. I am breeding a lot of hifin swordtails at my home now. I expect to get some good quality fishes within some months.
