i recently bought a bunch of shrimp and i found a little thing zooming across the tank which turned out to be a gammarus (or scud) unbeknownst to me. since there's only one i can't very well breed them but my grandfather's pond has tons so i have a few questions.
If placed in a heavily planted tank, will they eat all of my plants even if I feed them well?
Is there a way to rid them of possible parasites?
What food items can I feed them that are high in calcium?
