What type of fish/invertebrate that isn't normally or can't kept in aquariums would you love to have?

I personally would love to have a sea slug. I love how colorful and cool they look. Unfortunately they are expensive, hard to find and are almost impossible to keep alive. Some of them even poison your water and it's hard to tell the poisonous ones from the normal ones.

Some kind of squid. . .

A giant isopod.

I actually have looked into freshwater stingrays, they require a fairly large tank but I’ve always thought it would be cool to have. You can do clams if you have a fine substrate or crabs if you have a spot for them to surface. There’s a lot of neat freshwater invertebrates out there.

Nudibranchs are definitely up there on my list as well. I'd say manarinfish as well because I've heard they're difficult.
As far as not normally kept i got that covered with my seed shrimp gang lol. They really are great.
I guess fairy shrimp as well. I always kill em when I try em.

Just so expensive and difficult to source at the moment. Also, any of the large mouthbrooding wild bettas.
