okay first off, no one take any shots at my rudimentary CGI skills (i haven't studied or really practiced in several years) could this be done?
the main tank would be a 20 to 30 gallon aquarium, stocked with any number of different tropical community fish. the two in the back would be 3-5 gallon semi-circle tanks, each with a betta in them. the two internal tanks would have independent filtration, and heating would take place in the main area, which would in turn heat the internals through a blanket-like effect. the two internals would slide in and out on runners, and have their own lids that would protrude out from the surface of the water to prevent jumping but still allow the bettas access to surface air. is this possible?
