    Have any of you ever put these in your tank? I bought a small vial and have been adding a small amount here and there I figure maybe sone will hatch and the rest will be eaten. What do you think ?

    Unhatched eggs can cause Swim bladder disease if eaten. I was thinking about doing this but by hatching the eggs then placing the live brine in my fuge but i did some reading and saw that the shrimp need a higher salinity than you would have in your DT to survive long term. Also the eggs need to be kept suspended.

    Yeah I was really wanted to try this. A natural, live, continuous food source for the tank, but I reconsidered b/c of the risk of SBD and other diseases or parasites the eggs may be carrying.

    they are easy to hatch in either a shrimp hatchery or you can make your own out of a 2 liter pepsi bottle. they are best for your fish as babies, they quickly lose their nutritional value after that.

    Brine shrimp cysts can lodge in the digestive tract of some fish and block it. Also, the cysts are known to harbor bacteria at times.
    It is never recommended to have cysts, or hatching water, come into contact with your tank water, at any time.
    After hatching, rinse well in tap water before feeding them to the fish.
    It would be preferred to decapp the cysts, or at least sterilize them before hatching. Decapping provides quicker hatching with higher hatch rates.
    As for nutrition, the newly hatched nauplii are very high in fatty acids mainly due to the attached egg sack that is rapidly consumed. However, contrary to the "wives tales" out there, the protein content is good, ranging in the 50 to 60% percent range for those of Great Salt Lake cysts.
    The beauty of the brine shrimp is that they can be fed (after they reach the instar II stage where they develop a mouth and anus 8 to 24 hours after hatching) various things to be able to transfer it to the fish that consume the brine. You can add fatty acids, protein, pigmentations, vitamins, and even medicines.
    As long as you can micronise the food particles appropriate to what they eat, they will consume it. For liquids, you need to emulsify the liquid as in the selco type emulsions as the brine basically don't consume the water, but transfer the particles from the water into their digestive tract.
    For the most complete information available on brine shrimp (artemia) check out this site on the United Nations Manual on the Production and Use of Live Food for Aquaculture edited by the Artemia Reference Centre at the University of Ghent.

    Does decapping eliminate all diseases?

    There is no guarantee, but I know I don't use them without. I think there would be very little chance of a problem with decapped cysts though.
    Many years ago, I just sterilized the cysts with bleach, but when I found out the hatches came earlier with a higher hatch rate, I switched to decapping and never gone back.
