I have four shrimp (2 red cherry, 2 amano) in a cool-water tank. Do they have any special needs? So far they seem to be doing fine feasting on algae and scraps of food. Should I feed them shrimp wafers? I also read that iodine should be added... How?
I am thinking of getting a few more red cherries, but I first want to make sure I am taking care of these few shrimp correctly.
