Hey guys it's been a while - my turtle is doing very good. I'm interested though in tarantulas and so now I need to ask all the right questions before I make a decision. I've read about the different substrates and the lighting. Could I make a planted tarantula tank (would any plants be harmful)? would the lighting make plant life difficult. are there any special requirements that the pet stores website fail to tell me. nutritional things that are important or anything like that. other than crickets and the occasional pinky mouse. would a 20 high. be too big? are there any species that can be housed together(I may already know the answer but it doesn't hurt to ask) I really like red knees they are beautiful. if nothing else brag about yours so I get an idea what I'm looking for. I don't really want an aggressive species and a hardy one would be good.
