Fruit fly cabinet
For now this makes a great place to culture Drosophila melanogaster and waxworms.   The room radiator runs along the back wall making this a very warm spot for culture.  In the winter my D. hydei cultures have to be moved to a cooler place though.  Eventually I plan to move all of my insect cultures to a designated room and would like to sump the D. auratus tank above and house the sump and pump in this cabinet.
