What are the largest species of isopods available for culturing? Will adult White's tree frogs and Milk frogs take any notice of them? Wondered if they would make a beneficial addition to my frogs diets.

Also, can dubia and isopods be cultured together in the same container? Looking for something easy to raise at home that won't take up a ton of space or pose a risk for getting loose and infesting the apartment! @_@
