I got my T's, gunna go unpack them. Damon's either drunk or tweaking on monster hahaha:
Crystal Meph- you won't have to worry about adult sized containers for a bit (probably like 1year+) since most species grow pretty slow. If you decide on a species (and what your 2nd, 3rd, and 20th are gunna be) you definitely want then we could give you the most accurate info. Honestly, just pick something thats not known to be fast, and that's it, you'll be set. People say GBB's are more skittish and avic's can be finicky without the right humidity etc. etc., but from my experience they're all pretty darn easy as long as you exercise common sense and follow the care requirements/advice. Get something small too, so as it grows bigger you're already used to it. You don't want it so small that you're having to feed it roach legs or pinheads because thats a pain lol. I'd suggest around 0.75"-1" for whatever sling you get.
