Posthorn snail in the aquarium: all about posture and propagation: propagation

The pinworm bears the botanical name Planorbarius Corneus and is relatively easy to keep in the aquarium. The attractive little animals can live for several years and are peaceful companions who get along well with the other inhabitants in the aquarium. Due to its resistant properties, the post-horn snail copes well with temperature fluctuations and similar changes in the conditions.

General information

The post-horn snail belongs to the family of the Tellerschnecken and counts to their homeland nearly all tropical and moderate regions of the earth. For this reason, it can adapt extremely well to the conditions in the domestic aquarium. Thanks to the peaceful characteristics of the animal, socialization with most inhabitants in the aquarium is possible without any problems. However, post-horn snails are a prey to puffer fish, crabs and a few loaches, so the snails are eaten by them gradually. Thanks to a very high oxygenation in the blood, the post-horn snail rarely needs to breathe to the water surface. In this way, the animals can survive even in extremely low-oxygen waters. In general, the color of the snail shell is covered. But there are also colorful variations in the coloring, which can be beautiful color accents set in the aquarium.

As the only snail, it has hemoglobin in the blood, which leads to a reddish coloration of the body. In strong excitement or distress drops of blood are secreted.


The post-horn snail has no lid, which could give it extra protection. Therefore, this often retreats extremely far back into the housing and is then often no longer visible. For this reason, the aquarium should have a natural planting and furnishings as a welcome protection, otherwise the snail makes no special claims. The attitude is therefore relatively simple and can be carried out in the right conditions without any problems. Although the posthorn snail lives in the local waters as a cold water snail, but it can adapt very well to warmer water conditions in the aquariums in living rooms. If the water is too soft and poor in lime, the snails often gnaw each other's housings. In this way, the animals try to compensate for the calcium deficit for the construction of their own housing.

Post Horn pinto

The posthorn snails ceaselessly graze the soil in the aquarium for food leftovers and are therefore welcome help in the residual use in the aquarium. In this way, the hard-working animals help prevent rotting areas. In this way, there is a sustainable improvement in water quality. However, in the absence of food, the snail also eats away parts of plants, which also includes sprouting new shoots in the aquarium plants.
  • Omnivore diet, are among the omnivores
  • Eats algae, detritus and food leftovers
  • Preferably thin growth surfaces of algae
  • Avoid filiform and brush-like algae clumps
  • Spared the aquatic plants with sufficient feed supply
Tip: In order to ensure that the cornucopia always has enough food, it is advisable to cultivate growth algae for the inner glass walls of the aquarium. In this way, the animal always has enough ways to graze.


Often, posthumous snails come through newly purchased aquatic plants in the aquarium, in which eggs are stored in advance. However, the cute little animals have the reputation of transmitting harmful diseases and to eat the plants already growing in the aquarium, so this type of snail is often not seen with pleasure. However, the owner of the aquarium should concentrate on their good qualities, as the post-horn snail contributes an important share to a clean basin. The animal does not only eat algae and dead plant parts, but also dead fish are on the menu. In this way, the snail preserves the sensitive ecosystem in the aquarium in the long term. Therefore, always worth the attitude and the subsequent increase.
  • Simple breeding and propagation
  • Posthorn snails are hermaphrodites
  • Lay flat and disc-shaped spawning bales, with gelatinous attributes
  • Need smooth and solid ground
  • Hatching time depends on the water temperature
  • After days or weeks small snails hatch
  • These are already fully developed, but are still growing
Tip: If the conditions are too good and no natural predators live in the aquarium, then it can lead to an explosive propagation. Since this is not desirable in most cases and leads to a snail plague, appropriate countermeasures in the form of predators or the collection are necessary.
