Feed animals

Keeping frogs means producing live animal to feed them as they only eats things that move. For dart frogs it is typically fruit flies. I also feed them spring tails.

Lizards can also eat plant material, but prefer live prey. They mostly eat superworms, meal worms and crickets. The dragons also eat cockroaches.

The hedgehog will appreciate the same range of feed as the lizards.

To be honest, the millipedes and dairy cows are just as much for my entertainment as they are optional food. I think they may be consumed when small, but not after becoming a bit larger. 

Some of the feed animals I "rear" in vivo, that is they live in the same tank as those animals that are supposed to feed off them. However, as adults they are too large for the frogs to consume so then the can survive and reproduce in the same enclosure. 

Some I rear so I can provide extra feed, for example springtails to supplement newly out of the water froglets to ensure they are fed sufficiently.

Cockroaches are always handfed to the animals as they will otherwise escape and I risk having them free in the house. Crickets and fruitflies are always son the loose, so there is not much to do other than to accept them. There are many free-ranging spiders that appreciate the flies, including the charming jumping one (Salticidae).
