I read in this forum and in a link provided by someone in AC that Hydra can become a problem if you feed newly hatched brine shrimp to your fish. For that reason I have not been giving it to my White Cloud fry. However, there is a new product on the market called Instant Baby Brine Shrimp by Ocean Nutrition. They are basically newly hatched brine shrimp kept in some sort of preservative. They are not freeze dried, and the little jar has to be refrigerated after opening. Does anyone think that feeding this to my fry would bring about a "Hydra explosion"? I have read that hydra are actually always in water and that certain live foods causes them to flourish. Any suggestions? Has anyone had a problem with this product?
