I got this tank because I admire the design and functionality. It has a built in sump that even has room for a heater inside. Here is a video showing how the heater fits into the sump (kudos to pecktec for the video):

I plan to "instant cycle" it with some of my used filter media. I will dose some ammonia and see how fast it goes down. If it can't go through 2 ppm
of ammonia in 24 hours, I am going to keep dosing until it can. Dwarf puffers are messy eaters, and this is a relatively small tank, so I want to make sure it's cycled. I bought some freeze dried brine shrimp cubes, freeze dried krill, frozen bloodworms, and frozen daphnia. If these foods aren't accepted, I will just use pond snails as a last resort.
