Jasbus has you covered with good info. The only other thing I can see is your breeder male might have issues with other males in the tub with him, related or not. Once male rats breed, they really shouldn't be placed with other male rats in my opinion.

I will keep that in mind and an eye open. So far nothing probably bc the younger male might not be much of a threat. But if need be... Ive got 2 10 gallon tanks and 40 gallon long along with those totes. So will wait and see.
