Sorry about your frog passing away, ten years is a good age and so you must have gave him/her a good life. It interests me the way you kept the frog, it is very much different to what keepers normally keep them and sounds like a brilliant display. I thought a live planted tank would not work well for horned frogs due to the waste they produce but you've proved that it can. It interests me what size of tank this frog was housed in? I'd love to do something like this in the future.
