I agree with bynny on this one. Feeding froglets appropriately sized prey daily is fine. You’re not going to kill them with daily feedings. Power feeding adults however can cause a host of health problems and shorten lifespan. This has been widely reported and documented. Froglets though, need nutrition to develop. Feeding every 3 or 4 days is fine but so is daily. They are not going to eat themselves to death.

Wild froglets are produced during the rainy season because that’s the time when resources are most abundant. Given the species typically large clutch sizes and natural pressures, it’s in a froglet’s best interest to feed as often as possible and reach juvenile stage. Once the froglet stage is passed a stricter schedule is justified.

Also, as far as breeders go, there are only a few farms in the US that supply the majority of cb ceratophrys froglets to distributers for resale. So odds are at expos you’re dealing with a dealer and not a breeder. That individual may have a vast or limited knowledge which is then passed onto buyers. Ultimately, when creating a feeding regiment, a scientific understanding of the species natural history and referencing proven sources is preferable to vague hearsay and blanket statements.
