The Den of Drakaris -- lol I think I might have went a little overboard with the "Hybrid-Laboratory" theme 
Anyway I've recently replaced the jar on top of his shelter with just a layer of gravel -- he enjoys taking the stones from there in his mouth and throwing them over the side like bombs. About half the time I use a pink light and half the time a white light. Cleaning is pretty easy (except for his darn non-stop attacks) but he still has a few creature comforts compared to totally bare-bottom. 48"X22"X22", 80g/300 liters.
