Pothos, for all of them, its durable, my full sized Malaysian leaf frog cannot damage it, and he loves it. And why not pillow moss for the high humidity of the Leaf frog tank? and for the Grays why did you not use a higher watt bulb? you could use a flouresent and not produce heat. Pothos does grows well from cuttings. Can be bought everywhere, Supermarkets or Home Depot

Broms would also work for all except the Leaf frog for the most part, though these are not as commonly available and you will have to go to a greenhouse or buy online.
