So I'm planning on starting my first poison dart frog vivarium. I know the basics. So I have the option of using a 55 gal tank 48 inches long and 12 inches wide and 19 inches long. Or a basic 10 gallon tank I am not sure which one to use since it is my first vivarium. Now I would like to use abg mix as my substrate but it is a little pricey to fill the 55 gal tank so if I do go that route could I use the exo terra plantation soil that comes in 3 packs and the other half of abg mix. Another thing is I'm not sure what plants to use I want something that will give the effect of a grass and cover the substrate and other plants that will grow very very fast! And what is a good species of dart frogs that can stay together in big groups and will take advantage of all the space I can provide. Also I live in a very dry town so humidity will have to be in check constantly. And since I can't be home all day I was thinking of using the the exo terra monsoon will it be enough to cover the whole tank. And what would be a good lighting option that can have night options and help the growth of the plants. Thanks for all the help ahead of time.
