Simona, first of all I love your english it makes me feel like I'm on vacation in Italy and I'm trying to sound like the natives, so thank you.
I can't help you with your questions but I have two suggestions. 1st is to look under "search" and type in terrarium and see what comes up. You will probably get a lot of help from very knowledgeable people. 2nd Sometimes these smart people don't get to see your question because it's not up when they sign in, so you have to bump it up. You bump it up by adding something to your question even if it's just a symbol or a "hello". Good luck and ..A presto
