Cool tank! I just bought Chinese firebellies as well this week. One is healthy as can be and the other is sick and in a 'hospital' tank. The bamboo looks nice. Some java moss would complement it well. Your pet shop probably has a large selection of live underwater plants.
Oh yeah, I think the tank would do a lot better with a compact fluorescent bulb instead of the incandescent heat bulb. Look for the 10-13 watt DAYLIGHT COOL WHITE spiral bulbs. It produces much less heat and is probably better for live plants. Anyway, keep us updated! I'll post pics of my CFB in a new thread soon.
