What can live with sea monkeys and not eat them?
Sea Monkeys cannot live with fish. Guppies MAY be a possibility,
but I doubt that you will have Sea Monkeys when you go back to see
your aquarium. Also, Sea Monkeys are extremely small. And they
cannot live in anything larger than a gallon (except when they are
in a enormously-sized colony). Any fish WILL think of Sea Monkeys
as food. Also, only salt-water fish are physically able to inhabit
their tank in the first place.
Snails, however, can live with Sea Monkeys. A company known as
Little Aussie Products sells a product similar to Sea Monkeys
called "Itsy Bitsy Sea Dragons." They also sell "tank mates" for
Sea Monkeys/Dragons: Snails. They have multiple species of snails,
including: Teeny Weeny Winkles, Coco Snails and Blueberries.
Sea Bubbles are another small species which can live with Sea
Dragons/Monkeys. They are also sold by Little Aussie Products, and
are much smaller than even Sea Dragons/Monkeys.
I hope this helps!
