In English "fishbowl" can mean "a bowl for fish" or it can mean "a place where there is no privacy" (because it's made out of glass, you see).
So a "fishbowl community" is a community where everyone knows everything about everyone else.
Is there an analogue word/phrase/idiom in Russian for "fishbowl" (in the 2nd sense) and "fishbowl community"?

Thank you
