Advertisement Admittedly I'm a noob when it comes to T's. However I've kept and bred many species of Dart frogs for years. How many T keepers use a "bioactive" terrarium with microfauna, ie. Isopods and Springtails? Is it a newer trend among T keepers? How many T keepers use alternative substrates like ABG Mix? It seems as if straight coco coir is the norm. Old standard or behind the times? How many utilize live plants or leaf litter? I'm curious and hopefully this well be an interesting and informative discussion.
