Easiest frogs to breed..

[Tzunu un]

Starry Night Reed frogs (Heterixalus alboguttatus) are very easy and prolific as long as you have a water feature (doesn't have to be very large) in your viv......no need for a rain chamber for simulated rainy season....they spontaneously breed every summer for me in California even though it doesn't rain here all summer. The newly morphed froglets are large enough that they can eat D. melanogaster fruit flies immediately (and most of them D. hydei as well), and the adults do well on a diet of D. hydei fruit flies (but will also take other food prey up to 1/4" crickets).

They are a very easy beginner frog if you want to get the hang of breeding / tadpole care.

The eggs can be removed to a separate container to rear (more tadpoles develop /morph out) or the eggs can be left in the water feature in the viv (tadpoles develop in tank). The developing tadpoles will eat additional new egg clutches, so for higher numbers of tadpoles/froglets the clutches need to be removed when deposited and separated until hatching.
The tadpoles are easy to raise as a group in an aquarium with a sponge filter and a good quality fish food. The tadpoles are good climbers when they morph and have no trouble climbing up the glass side of the aquarium to be collected....the froglets/frogs are good swimmers so less chance of accidental drowning....thus there is no need to have a low water level in the aquarium or a slanted morph out set up (just a lid to keep them from escaping when morphed).

I have not removed egg clutches from the viv this year and I leave the tadpoles in the tank to morph out / compete as they would in the wild.....I raised too many separately last year so I'm letting nature take over. In the "leave in the viv" case, I do feed sinking fish food wafers periodically for the tadpoles, but they also eat any fruit flies that drown as well as excess egg clutches from the adults).

Other reed frogs may be similar but I only have experience with these.
