Ok, so I put 10 ghost shrimp in my 10 gallon quarantine tank yesterday. They went to town chowing down on the algae in the tank and they seemed happy. Today, I noticed some microscopic (not really, but EXTREMELY tiny) white things on the glass of the aquarium. I got out a magnifying glass and they appear to have tails. Are these shrimp babies? Or are they some kind of parasite?
