So i just got a female pastel and a male spider both are 1000+ grams. I have them in 2 41qt tubs and ive been offering them food about once every 3 days. Should i put them in a 28 or 32qt tub or just wait till they eat. The guy i got them from said they eat ft so thats what ive been giving them. Should i try to put a live rat in there. And whats some ways i can get them to eat.
