I feed mine fruit flies, crickets, wax worms and springtails. Fruit flies make up the bulk of their diet though. I hav eboth M. baroni and viridis. I think I might have two different kinds of painted mantellas though since some of them are blacl orange and green, while the others have more yellow than orange. I got them from two different sources, so I am wondering if I actually have two different speceies.
