I've gotten a recent crash course introduction into the breeding of Golden Mantellas, and the rearing of tadpoles. We're currenty breeding a group of 4.2 in a 10 gallon tank. The cage is misted 5 times a day, each misting lasts approx. 15mins. The males are seen combating, and heard calling on a regular basis. The male's call is short and similar to other Mantella species, which sounds more like a cricket, rather than a frog. The females get noticeably larger and swollen with eggs prior to deposition. Egg laying sites have been in the form of small, "Gladware" disposible tupperware containers filled with spagnum moss, with half the lid cut off. The frogs do prefer a darker, secluded hide to lay the eggs. We've noticed that once we see a few males guarding a nesting site, it's almost a garuntee the female has deposited a rather large mass (50 to 60 eggs) in the container. The eggs develop rather quickly, and usually start hatching with 7 to 10 days. A little trick on rearing tadpoles... keep them dark! They are extremely sensitive to light! We couldn't figure out why the tadpoles weren't doing well in the first batch until we read about the lighting. As soon as the first batch was kept dark, they litterally took off like weeds! It's been roughly two months since the first mass was laid, the back legs are fully developed and the front leg buds seem to be forming. Because of their small size and rather quick development, a little extra attention is needed with the eggs and tadpoles, compaired to that of their distant central/south american relatives. Good luck with breeding!
