A family, with one frog in the photo

Dart frogs are the family Dendrobatidae: dyeing frogs, thumbnails, phantasmal frogs, and a pile of others from Central and South America. This page cannot be one care sheet. The photo is a dyeing poison frog, Dendrobates tinctorius, which is one of the sturdier species people actually keep. The table's size range, 0.5 to 2 inches, is the family's spread. A half-inch thumbnail is not a tinctorius that failed to grow.

The shared needs are real. Most want about 72 to 80°F, humidity high enough that the quick facts say 80 to 100 percent, and a planted vivarium around 18 by 18 by 24 inches. They are diurnal and bold once they trust the tank. Care level is advanced because the humidity, the fly cultures, and the species differences all have to be right at once.

Toxins come from a wild diet

Wild dart frogs sequester alkaloids from wild invertebrates. Captive-bred frogs fed fruit flies, springtails, and isopods do not arrive poisonous, and they do not become poisonous on that menu. That is not permission to lick a frog or to buy a wild-caught one. Wild collection is how populations and diseases move. Buy captive-bred, ask which species is in the cup, and read a care sheet for that species before you add a second.

The quick facts call them territorial, and that shows up in a small tank. Many species fight if the tank is small or the sex ratio is wrong. A pair of tinctorius in a well-planted vivarium is a different project from a group of thumbnails.

Flies, fungus, and the bill

If the fruit-fly culture crashes, the frogs crash next. Keep a backup culture. A frog that stays dull, loses weight, or sits in the water bowl all day is in trouble. ARAV clinics are the ones who have seen this. The not-eating guide and the checker help you rank the afternoon. Animals run about $40 to $150 depending on species. The vivarium is the expensive object, often $300 to $600, and the lifespan line of 10 to 15 years means you will be culturing flies for a long time.

Dart frog questions

Are pet dart frogs poisonous?

Wild dart frogs get their toxins from wild prey. Captive-bred frogs raised on fruit flies, springtails, and isopods do not carry that toxicity. Wash your hands anyway, and do not collect wild frogs.

Is every dart frog the same to keep?

No. Dyeing poison frogs such as Dendrobates tinctorius are the common larger beginners-within-the-family. Thumbnail species are smaller, more territorial, and need finer prey. This page is the family, not a single recipe.

What enclosure do dart frogs need?

A common starting vivarium is about 18 by 18 by 24 inches, bioactive, 72 to 80°F, with humidity often 80 to 100 percent. Ventilation still matters. Stagnant swamp air grows fungus.

How long do dart frogs live?

The quick facts list 10 to 15 years for well-kept captive frogs. That is long enough that a fruit-fly culture is a hobby of its own.
