I'd like to put the insects and fish that I catch into aquariums and terrariums in my home, sort of like the bug/fish display except they are alive (even if they don't swim, they do their little animation like when they are in your menu). I'd like to feed them, but even without any interaction it would be nice to have them on display without killing them.I imagine it would be similar to the lifelike displays except you could build them (or order them from the catalogue)

If feeding was an option, I was thinking you would feed them with leaves, flower petals, acorns, or wildberries, maybe some salt water fish could eat coral or seaweed. Or, just a new item called "bug food" or "fish food" similar to feeding other animals.
