I had a large breeding group of Mantella Milotympanum a few years ago that I gave to another mantella keeper. Getting back into the hobby again and will receive a group of their offspring sometime to keep again. I had them set up in a 55 gallon vivarium that needed no care. natural live planted. Fed them waxworms, bean beetles, fruit flies, springs, etc, lawn plankton, etc. they did very well for me.
