you made a great choice by coming here.
you will get nothing but the best help.
and that cage looks amazing great job.
only thing i see would be the top of the pants need river rocks to cover the soil.
not a dumb question at all.
wire is your best bet. you can find a roll for a couple bucks at any hardware store and it will last you forever. tacs will either break or break the screen itself,
twist ties seem to be too big and flimsy and tie wraps don't give the freedom of movement that wire does.
Just make sure you get every piece of info needed even before you get your first.
Check my threads if you want. 100 threads of questions I asked before I got my cham.
15-20 is perfectly normal. I feed my 3.5 month old 15-20 plus 10 phoenix worms a day. They need to eat alot to grow. I don't know who told you 5 crickets a day but whoever did I'm sure their cham is hungry most of the time.
How many stress/scared patterns have you seen on your cham? A stick fell in my chams cage so I picked it up and went to put it back and when I looked up at him he had a weird new pattern I haven't seen before.
