I couldn't control myself. Today, I upgraded Vishnu's habitat.

From Nippon, I bought a 1-gallon acrylic tank. From Ocean Aquarium, I bought another Anubias barteri and a clump of young Java fern (Microsorum pteropus), each tied to small pieces of lava rock. I installed the heater I'd originally bought for the old 2G hospital tank, and added a thermometer.

From Justin, I also bought an 11W CF overhead lamp, but I think its AC adapter is faulty: it hums loudly and the bulb emits lots of heat, which it should not. I'll return the lamp tomorrow. In the meantime, I'm using the 7W incandescent lamp from the 0.5G tank, which actually gives a nice effect. I could keep using it since the Java fern and Anubias are both low-light plants, but I'd love to have something a little stronger (though not nearly as blinding as the 11W CF). I may go with a household fixture instead of a lamp designed for the aquarium.
