How often should I change the water?

Partial changes every week or two are the baseline. Change sooner if water is cloudy, smells off, or has leftover food. Replace 30–50% with temperature-matched water — avoid full dumps.

How often should I feed?

Tiny amounts about three times per week. If food is left after a few hours, or water clouds, you are feeding too much.

What temperature should tadpoles be kept at?

Most dart frog tadpoles do well at 68–78 °F (20–26 °C) in the water. Measure the cup water, not just room air.

Raising Dart Frog Tadpoles

Northern Darts tadpole rearing from arrival through metamorphosis — the same care we print on every shipping insert, expanded for day-to-day husbandry.

When You Open the Package

A calm, careful start reduces stress and shock. Open indoors, away from direct sun and drafts. Let the film canisters sit out for 15–20 minutes near their cups so temperatures can equalize before you open them.

After acclimation, move tadpoles into their clean cup, deli container, or tadpole system. Do not rush the first feed — give them several hours to settle first.

If anything looks wrong (injuries, severe lethargy, or abnormal swimming), take clear photos and contact Northern Darts right away at Northerndarts101@gmail.com.

Water Quality

Clean, stable water is the foundation of tadpole health. Use dechlorinated tap water (aged 24–48 hours or treated with a conditioner) or RO/distilled water that has been remineralized with a tadpole-safe mineral additive. Avoid long-term use of straight RO or distilled water with no minerals — it is too soft for sustained rearing.

Do partial water changes every week or two as a baseline. Change more often if the water looks cloudy, smells off, or if there is excess food. Remove 30–50% of the water and replace it with fresh, temperature-matched water. Never dump the entire cup at once — full resets can swing pH and temperature hard enough to stress or kill tadpoles.

Waste and uneaten food collect in the bottom corners and under surfaces. Use a small airline tube or turkey baster to gently siphon debris during changes. Good flow or gentle aeration helps keep water oxygenated and reduces waste buildup.

General temperature guide for most dart frog tadpoles: 68–78 °F in the water itself, not just the room air.

Housing

A proper setup keeps tadpoles secure, comfortable, and easy to care for. Use individual deli cups or small containers for best survival and easy monitoring. Ameerega, Epipedobates, and Hyloxalus can be kept communally when space, filtration or change rhythm, and observation are strong enough — most other dendrobatid tadpoles do better alone.

Keep water deep enough to swim comfortably, but not so deep that late morphs cannot reach the surface. A practical depth is about 2–3 inches; lower the water when the tadpole is ready to transition to land.

Label each cup with species (if known) and date. Keep cups in a sturdy rack or container so they cannot tip. Keep them out of direct sun, vibrations, and high-traffic areas. Good airflow helps prevent mold and stagnant air around the rack. A clean, organized shelf makes daily checks faster and misses less.

Temperature

Consistent, moderate warmth promotes steady growth and healthy development. The ideal range for most dart frog species is 68–78 °F (20–26 °C). Keep temperatures stable and avoid extreme daily swings.

Use a reliable thermometer in the water — cup water often runs warmer or cooler than the room, especially on upper shelves. Avoid heaters placed directly in cups. If heating is needed, warm the room or place cups in a warm, monitored area.

FAQ

Can tadpoles be kept together?: Individual cups are safest for monitoring and survival. Ameerega, Epipedobates, and Hyloxalus can be kept communally when husbandry is solid. Most other species are better raised alone.
How often should I change the water?: Partial changes every week or two are the baseline. Change sooner if water is cloudy, smells off, or has leftover food. Replace 30–50% with temperature-matched water — avoid full dumps.

Hygiene & Troubleshooting

Watch daily and act early—small issues become big fast.

Cloudy water: Usually waste or overfeeding. Reduce food and do a partial change.
Surface film: Caused by leftover food or oils. Remove excess food and increase water changes.
Gasps at surface: Low oxygen or poor water quality. Increase aeration and do a partial change. This can also happen due to high temps.
Lethargy or isolation: Check water quality and temperature. Make sure the tadpole is eating.
Death after feeding: Often caused by portion size or poor water quality. Don't overfeed and keep water clean.

Temperature

Consistent, moderate warmth promotes steady growth and healthy development.

Ideal range: 68–78 °F (20–26 °C) for most dart frog species.
Keep temperatures stable; avoid extreme daily swings.
Use a reliable thermometer in the water.
Avoid heaters placed directly in cups. If heating is needed, use a room heater or place cups in a warm room.
Water in small cups can heat up faster than the air—always check the water temp.
Never place cups on windowsills or in direct sunlight. Overheating can happen quickly.
Stability is more important than speed. Warm + consistent + well-fed = healthy growth.

Feeding

Small, frequent meals keep tadpoles growing without fouling the water.

Feed high-quality foods such as: tadpole diet (e.g., Repashy Soilent Green), spirulina powder, algae wafers, or quality fish flake.
Offer tiny amounts 3 times per week. A very small pinch is usually enough. (2–3 large flakes, 2–3 tiny granules, or similar size)
All food should be eaten within a few hours. Remove any leftovers before the next feeding.
Cloudy water or an ammonia smell = too much food. Cut back and do a partial water change.
Vary foods for best nutrition. Spirulina and vegetable-based foods promote healthy growth and development.
Avoid protein-heavy foods (like bloodworms or brine shrimp) as a staple for tadpoles. They can be fed but not as the main diet.

Toward Metamorphosis

As tadpoles grow legs and their tail shrinks, their needs change.

Timing varies by species and temperature—anywhere from several weeks to several months.
When front legs appear and the tail begins to shrink, water can be shallower.
Tilt the cup or add an object at the water line that the metamorph can climb onto. If they have nowhere to climb out of the water, they can drown.
Prepare a humid “morph box” with damp paper towel, sphagnum, or leaf litter.
Once the tail is almost gone, move them to the morph box. They will emerge and absorb the rest of the tail.
Keep the box humid (not soggy) and check daily.
Once the tail is completely absorbed move them to a growout and begin feeding with springtails.
Froglets are ready for flies at 1–3 weeks depending on species and temp. They will not eat until the tail is completely absorbed.
