No pet frog makes record-keeping matter more than a poison dart frog, because in this hobby identity is everything. Dart frogs are kept by species, morph and locality — populations that may look nearly identical yet come from different places and must not be crossbred — so the first records you keep are the frog's exact identity, its breeder, and its lineage as far back as the breeder can trace it. Lose that paper trail and a valuable, carefully bred frog becomes an unlabelled animal no responsible keeper can breed or rehome with confidence.
Identity, morph and lineage records
Write down the species, the morph or locality name exactly as the breeder gave it, the breeder's identity, and any line information — which breeding group the parents came from and whether the frog is related to others in your collection. Keep the purchase paperwork with it, and photograph the frog's pattern from above; individual markings corroborate identity if frogs are ever mixed up during a move or a rehome. If you keep several morphs or species, keep their records strictly separate and label enclosures to match, because a note filed under the wrong population is worse than no note at all.
Fruit fly cultures and feeding notes
A dart frog's food supply is a living culture you manage, so log it like one. Record when each fruit fly culture was started, which type of fly it holds, when it begins producing well and when it fades, so a culture crash never coincides with an empty shelf and hungry frogs. Feeding notes should cover how often the frogs are fed, how eagerly they hunt, and the dusting routine you follow for the flies, recorded as your vet or breeder advised. Frogs that stop appearing at feeding time or lose their quick, snapping hunt are showing you a change — and in a densely planted vivarium, the log may register it days before your eyes do.
Calling, eggs and tadpole records
If your frogs breed, the record becomes a family history. Note when calling starts and which male calls, courtship you witness, where eggs are laid and how many, and whether the parents transport tadpoles to water or you raise them separately. Track each clutch through to froglets, recording losses plainly; patterns in which pairs produce thriving young, and which clutches fail at the same stage, are the most useful breeding knowledge a keeper accumulates. Those outcomes, attached to accurate lineage notes, are exactly what the next keeper of any young you sell or gift will need — record them as carefully as you wished your own breeder had.
Vivarium notes that complete the file
Finally, keep a light record of the vivarium itself: humidity behaviour, misting rhythm, plant growth or die-back, and clean-up crew fortunes, because the frogs' health is inseparable from the living enclosure's health. Bring the whole file together when the frogs see a vet or change hands.
