Mystery Snail Eggs

Mystery Snails tend to lay clusters of eggs above the waterline, this is because the eggs don’t really need a lot of water just a bit of moisture. Keep in mind that the eggs can be both fertilized and unfertilized.

You have the option to remove the cluster of eggs from the tank, or you could just let them be.

The eggs that Mystery Snails lay are mostly grape-like structures and can be found in clusters. The snails usually lay the eggs on the side of the aquarium or on the cover of the tank.

In order to develop properly, the eggs need an environment that is not dry and has a heat source. Healthy eggs should hatch in about 2 to 3 weeks, so it’s best to keep an eye on the cluster. If they do not hatch in the period defined, then go ahead and remove the cluster from the tank gently. Proceed by breaking the cluster in half and check if there are any babies inside.

If you see small baby snails, then that means that the eggs are ready to hatch, and the small snails are on their way to take on the world. On the other hand, if there is no baby snail insight, then that means that the eggs are infertile, so you can go ahead and discard them.

During the second week, examine the eggs, if they should appear to be a bit darker in color if they are healthy. There are many ways that you can adopt in order to hatch them.

If there isn’t any fish around, then its best to just leave the eggs where they are until they hatch. Moving eggs can sometimes be tricky and can damage them.

When eggs are first laid, they are soft and milky, they then proceed to harden and change in color in the first few hours. Mystery Snails lay eggs above the waterline, so never put them underwater as the embryos may drown.

Hatching the Eggs

There are several ways that you can choose from to hatch the Mystery Snail eggs.

One way is to buy a smaller box, which you can use as a birthing tank. You could use the tank to just hatch the eggs or house them for a longer period of time.

So all you need to do is get a small plastic box and then add a little water into it. Then take a plastic sheet and then attach it to the sides of the box in a way that it hangs in a U shape inside the box but does not touch the water.

Just make sure that the surroundings of the tank are warm, you can even opt for placing a heating pad in the tank. Keep the conditions the same until the eggs hatch, and the snail babies venture into the world.

Another thing is incubating the eggs in the same tank. In order to do this, you need to get a net breeder and install it on the shorter side of your aquarium; the tank should now be partitioned. You don’t have to decorate this part of the tank the same way. Attach a plastic canvas on top of the tank on the partitioned portion and then place the eggs on it.

Remember the plastic canvas should be a little under the water; this will ensure that the eggs get the nutrients that they need. Once all this is done, you should keep the conditions constant until the eggs hatch. This is a great way of you plan on keeping the Mystery snail babies in the same tank.

Mystery Snail Reproduction

Mystery Snails, like most Freshwater snails, are hermaphrodites. This in layman terms, means that the snails can carry both eggs as well as sperms, and they do not really need a mate in order to reproduce. Freshwater snails mostly lay eggs about two weeks after fertilization takes place.

Baby Snail Development

On average, about 20 to 50 snail babies hatch successfully. The shell of the baby snail develops from the time it is an embryo inside the egg. If the conditions are favorable, it takes about 2 to 3 weeks for the eggs to hatch, and the baby snails that emerge from the hatched eggs have soft shells. This is why they need to have a steady diet that contains calcium so that their shells can become strong and hard. The embryos begin by consuming their eggs before they are even hatched.

In addition to the soft shell, the baby snails also have a transparent body that slowly and gradually acquires color as well as strength as the baby snail grows. The first color is usually blue but then in changes into brown or any other color that characterizes the snail species. Snails have a tendency to grow at an insanely fast pace, but most of the babies don’t even reach maturity. This high death rate is due to the fact that snails have numerous predators, and baby snails are the most vulnerable and easy prey.

The shells of the snail continue to grow over the course of the snail’s life, the rings on the shell help to indicate the age of the snail.

Baby Snail Care

Caring for snail babies is not really that hard. They live off the algae in the tank and also love commercial foods that contain shrimp. Snail babies tend to produce a lot of waste, so you may need to clean your tank on a regular basis. Keep a check on the pH level as well as the Ammonia Level in your tank. The level of pH in the tank should be about seven, and the Ammonia level should be zero. You also need to remove any other fish in the tank, as they might end up eating the baby snails. You can enhance their survival by gently sucking the baby snails out using a turkey banister and transporting them into another tank.


How do you kill mystery snail eggs?

The easiest way to kill snails, as well as their eggs, is by using bleach. Prepare a soaking solution using half a tablespoon of potassium permanganate and one gallon of water. Soak your tank for fifteen minutes and then rinse well before planting the tank.

How to control the population growth of snails in my tank?

The best way to control the population growth of snails in your tank is by placing snail-eating fish in your tank. Yo-Yo Loach or Clown Loach love to devour snails.
