A car gets "fish tanked" when some idiot leaves their sunroof open during a terrential downpour. The best form of the "fish tank" is when water flows out your door when you open it.

When a female gets oral sex while taking a dump in the upper tank of a toilet.
It’s like a female blumpkin mixed with an upper decker.

Sara gave me a blumpkin last week. I returned the favor by hooking her up with a dirty fish tank in the restroom at the mall.
