Hey, I'm new here, and looking to start a dart frog terrarium, I am not new to herp keeping, but have never kept dart frogs before, if possible, can you guys reccomend a short list of equipment for me to have, mostly if you could reccomend substrate, especially. Also, I was wondering if an exo Terra terrarium or my 20 gallon tall would be a less/more expensive/simpler option - the frogs I would be keeping would just be azures. Thanks mangs.
