Near-final plan for the new aquarium setup (Patreon)

Subject to change, but I doubt if much will at this point. Because of the double thiccness ballast pods these will also be inter-operable with megahab, should I ever have access to a body of water I can submerge it into. The water bottle is internal this time so it can be removable, which is more durable than mounting the cap permanently and simplifies refilling vs how it currently works. 

Also, it's very likely I will replace my hams with mice as the hammies die of old age, for the simple reason that mice are safe to cohabitate. I think the new larger modules will be able to support 2 or 3 mice comfortably.
