Update: I switched out the tanks to one of those wire racks that can hold a lot more weight. I also fashioned my own plastic tops for all the tanks. I liked the ventilation the plastic mesh had, but the water temperature wasn't staying that stable at night.
I know the shelves look like they are bowing in this picture, but I discovered one of the legs was slightly unlevel. It is completely level now and 1000x sturdier than the last shelf.
The tank in the upper right hand corner just holds extra plants and driftwood, there's no fish in it.
You can see the clear plastic lids. Every fish now has mossy driftwood and anubias plants to rest on. Two new fish:
Poseidon: He came from a girl at my apartment building who asked me to care for him. He's a blue VT and has some sort of weird lip deformity. He's afraid of the camera.
Camila: I received her from a big chain petstore. The employee was concerned as her fins were rotted and clamped, and she was lethargic. She's a completely new fish today...still afraid of the camera though! Red cambodian
Next up is figuring out some sort of reflector structure for the lights so they don't shine every-which-way but in the tanks. I'm thinking like a simple wooden 4 walled box structure painted white inside. Like this:
