Why do garbage bins have rats?
I bet the garbage bins on the ISS don't have rats.

I remember hearing the sound of sliding metal just before the dianoga disappears and Luke resurfaces. I always took that to be that it had some hatch it swam to before the compactor operated.
Makes sense. Not much point in compacting water. Although you'd have to assume that the thing could fit through holes designed to sluice water.
Of course, there's no actual need to presume any given creature survives outside of R2-D2's divine intervention. Maybe that was it's life cycle in that particular niche--born as a microscopic larva thing, grow, reproduce (asexually, hermaphroditically, conventionally sexually?--could be more than one), give birth, attack jerks who invade environment if necessary, get crushed once a month, hope children have a better life (they won't, because they'll all be ionized gas in a few days).
