Worms
An Aquatic Snail is an Decomposer
Platypuses do not eat earthworms or other terrestrial worms. They eat aquatic annelid worms.
Occasionally. My newt, which I caught from the wild, has eaten some. Wax worms are for less aquatic newts, but Blood worms are better for more aquatic/aquatic newts. Also, Wax worms are better for newts because of their soft skin. The rough outer exoskeleton of the Bloodworms can damage their bellies.

Catfish eat whatever is available, worms, fish, crayfish and any type of aquatic life they can find, they are not picky eaters.
