So i purchased a standard ten gallon tank and stand. I am planning to make this tank horizontal not vertical. My first question is what type of dart frog do you think i should get/ how many of them should i get. More importantly what is involved in setting up the vivarium. I would like to have a waterfall/ a pool at the bottom of the tank. How would i do this? Are there any other vivarium basics i should know? Thanks. Sorry i'm a noob.
