I have something in my fry shrimp tank there white and the size of a pin head I assume they came in on a shipment of moss I ordered. How do I identify them when I cant really see them what are common hitchhikers and do I need to worry about them eating all the food my fry need any help would be greatly appreciated I tried to film and take pics but there too small for my phones camera to get a detailed picture here is the only one that focused
