Large fish won't fit in a 20g, a 20g is relatively small tank. Large fish could also eat shrimp and small frogs! Tortoises are terrestrial animals, you're thinking of Terrapins, many of which get very large and will potentially eat any fish! Freshwater "lobsters" are called Crayfish and the general rule is if it has big claws it will eat whatever it can catch in said big claws, including fish.

There are a lot of compatibility issues in a "mixed" tank like that you need to consider.

Some larger peaceful shrimp species such as Amanos and Bamboos work with small peaceful non-nippy fish, but avoid long-arm shrimp as they'll eat fish!

Frogs are best in species tanks. African Clawed Frogs get very large and will eat fish.

edit: Freshwater "clams" or mussels can be tricky to keep as they filter feed so water quality needs to be perfect but they need to be fed small enough particles to eat - very regularly.

As for snails, many "common" ones like Ramshorn, Malaysian Trumpets and Pond/Bladder snails are hermaphrodites and will reproduce to plague proportions. Others like Apple Snails need a male/female counterpart to breed but can also get quite big. Nerites can't breed in freshwater. All snails are surprisingly messy!
