How to raise frog eggs
Raising frog eggs from babies to adults can be fun and educational. (two frogs image by Dragana Petrovic from

After your frog has laid her eggs, help her care for them and raise them to maturity. Sometimes frogs lay their eggs in less than ideal environments, such as in water with lots of dying tree matter or other objects. Step in and help the mother keep the eggs safe in your aquarium with a little bit of knowledge and effort.

  1. 1

    Leave the frog eggs alone if they have laid their eggs on land near the water. Some frogs choose to do this, so do not dip them in water after the fact. You may spray them with water mist every day to keep them moist and fungus free. Justin C. Touchon of Boston University has found that yellow tree frogs lay their eggs above water in the shade and below the water in the sun. Unless the frog eggs are in danger, do not move them.

  2. 2

    Make a suitable environment for your frog eggs. Purchase a regular aquarium from your local pet shop. The container should be short and wide to maximise the oxygen. Large new plastic containers can also be used. Fill the tank with clean water (rainwater collected as it falls is preferable) or water from a stream that has been boiled and cooled.

  3. 3

    Place river sand from a nontidal part of the river at the bottom of the container. You should also provide a few underwater plants, which can be purchased at pet stores, to give your eggs the maximum oxygen. Plants with lots of leaves that float to the top of the water are the best choice.

  4. 4

    Wash the leaves you'll put in your tank and then boil or freeze them to kill any bacteria.

  5. 5

    Position your tank near a sunny window for an hour or two a day to process vitamin D. Keep them in the shade the rest of the day so the water doesn't dry out.

  6. 6

    Move the frog eggs into your tank only if they are in a dangerous place or with too many rotting materials; otherwise, observe them in place. To move eggs, dip a clean, new plastic container into the water and transfer the eggs into your tank. Be sure to keep any leaves the eggs are on with them in the new water. If they are on a leaf attached to a plant, cut the leaf off of the plant.

  7. 7

    Test the water the eggs are in regularly. The water should remain at a pH of 5 and should be free of phosphorous, nitrite and ammonia. You can purchase aquarium pH test kits at your local pet store.

  8. 8

    Keep fungus off of the eggs by spraying them with antifungal spray, using one third of what the bottle calls for.

  9. 9

    Purchase a good chloramine remover and change at least 15 per cent of the water once a week, keeping the water at a temperature between 22.2 and 27.7 degrees C (72 and 82 degrees F). Continue this as the frogs morph into tadpoles.

Tips and warnings

  • Never add snails to your aquarium. They will compete for food sources and may carry bacteria that will cause deformities among your colony.
