Accidental Axolotl Eggs: What to Do With the Babies

By The Bognook Team · written & researched by amphibian keepers🔍 Keeper-reviewed for accuracy

Axolotls breed readily — sometimes very unexpectedly — and a lot of keepers wake up to a tank suddenly full of eggs they never planned for. First: take a breath. You have a couple of weeks before anything hatches, and this guide walks you through the honest options.

🖤 Keep the water right through all of this — babies are sensitive to water quality. The free Water Interpreter and the cycling guide will help.

First, an honest reality check

A single axolotl clutch can be hundreds of eggs. Raising even a fraction of them means a lot of separate containers, daily water changes, and a steady supply of live food for weeks. You do not have to raise them all — and deciding not to incubate a huge clutch you can’t home is a responsible choice, not a failure. The kindest plan is to decide early and line up homes before they hatch.

If you want to raise some

1. Separate the eggs. Adult axolotls will eat their own eggs and hatchlings, so gently move the eggs (usually laid on plants or the tank wall) into a separate container of cool, dechlorinated water. Remove any egg that turns white and fuzzy — it’s fungused and can spread.

2. Wait for the hatch (~2–3 weeks). Keep the eggs cool, clean, and gently oxygenated. Newly hatched larvae live off their yolk for a day or two before they need food.

3. Feed live food — only. Hatchlings only eat moving food. The standard first food is live baby brine shrimp (microworms or daphnia also work), once or twice a day. That much live food fouls water fast, so babies need daily water changes. As they grow, move them onto chopped blackworms and small earthworms.

4. Manage the cannibalism. Axolotl larvae bite each other’s gills and legs — they snap at anything that moves. This is normal, not fixable by training. Separate them by size, reduce crowding, and keep them very well fed. Lost limbs usually regenerate in a healthy axolotl, but spreading them out prevents the problem in the first place.

Rehoming responsibly

You will, realistically, end up with more axolotls than you can keep. Well before they’re ready to go:

  • Reach out to local axolotl/keeper communities, exotic-pet groups, or a reptile & amphibian rescue.
  • Be honest with new owners about the (surprising) care needs — cool water, cycling, live food.
  • Never release axolotls or dump them in a pond, lake, or drain. They’re a captive species (critically endangered in the wild, not native to your area), and releasing them is harmful and, in many places, illegal.

💚 An accidental clutch is overwhelming at first, but you’ve got time and options. Decide what you can realistically care for, raise those well, and rehome the rest to people who’ll love them — that’s the responsible, kind path.

Common questions

My axolotls laid eggs — what do I do first?

Decide honestly whether you can raise them, because a single clutch can be hundreds of eggs. If you want to raise some, gently move the eggs (they are often laid on plants or tank walls) into a separate container of cool, dechlorinated water — adult axolotls will eat their own eggs and hatchlings. If you cannot commit to raising a large number, it is kinder to not incubate them all; line up experienced keepers or a rescue before the eggs hatch rather than after.

How long do axolotl eggs take to hatch?

Axolotl eggs usually hatch in about 2 to 3 weeks, depending on temperature (cooler water is slower). Keep them in cool, clean, dechlorinated water with gentle oxygenation and remove any eggs that turn white and fuzzy (those have fungused and can spread to healthy eggs). Newly hatched larvae live off their yolk for a day or two before they need feeding.

What do baby axolotls eat?

Only live, moving food — hatchlings will not take dead or still food. The standard first food is live baby brine shrimp, with microworms or daphnia as alternatives. They need feeding once or twice a day, and because that much live food fouls the water fast, baby axolotls need daily water changes to stay healthy. As they grow you can move them onto chopped blackworms and small earthworms.

Why are my baby axolotls biting each other's legs off?

Axolotl larvae are cannibalistic — they snap at anything that moves, including their siblings' gills and limbs. This is normal behaviour, not aggression you can train out. The fix is to separate them by size and reduce crowding: raise them in small groups or individually, keep them very well fed, and give them space. Lost limbs often regenerate in a healthy, well-fed axolotl, but prevention through separation is far better.

What should I do if I can't raise all the axolotl babies?

That is a very common and responsible thing to realise — clutches are huge and raising them is a lot of work. Reach out to local axolotl keeper communities, exotic-pet groups, or a reptile/amphibian rescue to rehome hatchlings or eggs. Never release axolotls or dump them in a waterway: they are a captive/endangered-in-the-wild species, not native wildlife, and releasing them is both harmful and, in many places, illegal.
