ok so i have a rack system on the way but it wont be here for another 2-3 weeks... i have 4 balls right now and another on the way that should be here in the next two days. depending when they ship it out. i dont have the money to go get another tank and heat pad right now so im wondering is it ok to house them in the same tank until the rack arrives, and if so males with males or females with females?

thank you for you answers ahead of time
