Just asking for opinions, I've heard that Faunariums are horrible for maintaining humidity and are therefore not recommended, but these things called RUBs are better. Sorry if my questions seem silly but I am new to pets in general, and I am just gathering all the information I can possibly receive before going to get my first BP. I would get a viv, but in my current house there's no room for it unlike a RUB. Another question is, what size RUB or Faunarium is recommended for Juveniles ( use L please! ) and when should I upgrade the size of the RUB, and to what size? Many thanks!
