Except not really. There are no fully aquatic and fully freshwater hermit crabs. Many of the terrestrial and brackish species can survive a few weeks in freshwater, but not for long periods of time.
The freshwater jellyfish are hard to impossible to get, only last 30 days, and only the nonmobile form can reproduce.
The sponges and corals, with the exception of the not well known and completely unobtainable ones from Lake Baikal (that would most likely need very high velocity, chilled water) never grow more than a couple of inches across, never get nice colors or long arms, do not harbor photosynthetic stuff in themselves, do not grow branches, and are entirely filter feeders.
The jelly fish being hard to obtain, do you speak from experience of trying to get some?
Yes. They only exist in late summer, they do not exist in New York, and they cannot be shipped.
I found a jelly in a lake in central Michigan didn’t even know they existed prior
How do they only exist at a certain time of the month... It can't be like they go extinct then just magically come back to life. Do they lay their eggs and then die and the eggs hatch months later?
The jellyfish is a non-functioning part of their lifecycle. It only reproduces in China. (Wikipedia says the appearances are erratic, but most eyewitness accounts I've read say only in late summer.)

Actually there are fully freshwater hermits, they just aren't readily available.

there are several threads here about freshwater jellies, they and freshwater sponges tend to do best in ponds than tanks.One member had them in his pond with peacock bass, he believes the juvenile stage hitchhiked on his water lilies
