My all in one question need feedback thread

Finally after scouring fauna I found a graziani line female pastel locally. Born 8-2010 breeder says she is 150-160 grams feeding once a week. I want to know your opinion on a few things.

What size tub to get her and how long it should fit her?
Should I feed her every 5 instead of 7days?
What size prey should she be eating?
Exo Terra desert uth or zoo med uth? Small size for the tub

I am going to buy everything tomorrow on my way home from work. I will get tub, small uth, paper towels, ramekin style water dish, hide? Probably a plastic flower pot or cereal bowl. Accurite thermo, lutron lamp dimmer.

Next month I will buy a ranco or Johnson t stat so I don't have to fiddle with a dumb dimmer. I am going to get her Saturday so I need to
get this tub setup soon.

18 quart tub, which should fit her until she's 300 grams, then switch up to a 32 quart.

I feed my holdbacks every 5 days, and my girls have now exceeded 1500 grams at age 2, so it's up to you. ;)

Feed prey as big around as the widest part of the snake's body--for a snake that size, a large fuzzy or small crawler rat, probably.

I would get a UTH from Big Apple Herp that is safe for use with a plastic tub. Or use a heat cord (they sell those as well, and they're pretty cheap). I'm not sure you can find anything local that is safe to use with plastic bins. The undertank heaters found in most pet stores specifically state they are only for use with glass tanks. Read labels carefully.

You can take a risk with one, but I certainly wouldn't recommend making a long-term habit out of it.

I would get a 12 to 18 quart tub and feed a rat pup every 5 days! I would go with the zoo med as they are built better and heat better!
