So as I inch forward toward my first shelldweller tank, I have more and more questions. Most can be answered through searches or videos - but I have yet to see anything regarding the vacuuming of shelldweller tanks.... specifically once a colony gets started with fry. Do y'all resort to solely water changes? What happens to the detritus then? Siphoning other tanks isn't difficult, as there are no hidden places for fry to hide (such as shells). This is particularly confusing to me when the bottom of the tank is solely a shellbed - no substrate.
