Newbie questions:
1) I save specimens in a Petri dish. Should I keep the cover on or cover off so there is oxygen?
2) Should I keep the specimens (Ciliates, Crustaceans, etc.) in the dark or under a “grow lite)?
3) I sometimes get sand when collecting specimens from a pond. How can I filter the sand out while keeping the specimens.? I tried coffee filters, cloth, paper towels, etc.
Thank you in advance.
