Thanks, would love to see an update.
One more question, I feed my newts blackworms/tubifex as a staple, is there any fear of them getting into the substrate and fouling it up? I kept a little bit of gravel with my H. orientalis for a while and this happened. The worms lived for quite a while in the gravel and would serve as a snack once in a while for the newts hunting them, but would eventually die and foul up the substrate. This could be because I didn't have any cleanup critters in there or any plants that were actually rooted in the substrate (I only had free floating elodea and java moss. Would a well established planted aquarium plus the critters take care of this for the most part?
