This morning I was vaccuming one of my aquariums. Before dumping out the water I noticed someting very, very tiny swimming at the bottom of the bucket. I found a pic on a google search and found out they are baby shrimp. What I have not found is how to take care of them. What I have done is move them to a 6.6 gallon bookshelf tank. I do not know where to go from here now. Can anyone advise, please? I should add that I am not sure what I should be feeding them, I am hoping for some of them to survive...
