is it safe for heat tape on this?

two are in one tub one in another they have heat mats these are loans for breeding with my males and the guy was supposed to supply me with tubs but did not so im tryn to do the best i can for these girls he had them in 10 gallon tanks a big no no i dont have any females bigger than 1500 grams that i own so i dont have big tubs for these girls

Get larger tubs asap. You shouldn't agree to a breeding loan is you can't house them comfortably.

the sad thing is their is a written contract for the owner to supply housing for them being i told them i didnt have the correct size tubs they said they would bring them and never did so im just going to get the stuff they need mean while i also stated if they didnt follow the contract that they would have to go back with the owner with no breedings so ima see where it goes but a little pissed at them not following through:mad:
