Porcelain Limpet Snail (Septaria Porcellana)

Septaria Porcellana is also known as “Porcelain Limpet Nerite Snail”, “Teppich-Schnecke” or “The Marbled Limpet Snail” is a snail species belonging to the Neritidae family. This snail was named by the famous Swedish zoologist and botanist Dr. Carl Linnaeus in 1758.

Although some sources indicate that Septaria Porcellana’s natural habitat is in Thailand, it also lives in India, Taiwan and various Southeast Asian countries.

The name of this snail is derived from “Septaria” which is the cement-like substance used in buildings in ancient Roman times, and “Porcellana” meaning porcelain-like.

Septaria Porcellana can reach 2-3.5 cm in length. The shell structure differs from other snails and is in the shape of a tent. Compared to other snails of similar size, they create less biological load on the aquarium and produce less waste with their smaller and compacted body structures. Also, they are suitable for nano aquariums due to their low bioload.
In the aquarium, they especially prefer glass surfaces.

Septaria Porcellana can adhere strongly to glass surfaces, and their shell structure is highly protective for predators. Due to this reason, they can live in harmony with wide types of different aquarium creatures while compared to other snails. Their specific shell colors are usually yellow and cream. There are also black lines on this shell like a spider web.

Water Parameters

Temperature: 23-28°C
pH: 7,5 – 8,0
Hardness: 2 – 12 dGH

Although the optimal pH range seems narrow, they can also tolerate lower pH values. Some sources have specified a minimum pH value of 6 for this snail to survive. On the other hand, tank dimensions are substantial for a healthy life. As a simple calculation, 7,5 liters of water volume is necessary for each snail.

Due to the different shell shapes from other snails, it is so hard for them to turn back to normal again when they turned over. High currents or other reasons in the aquarium can cause them to turn reverse. In such cases, human intervention may be necessary for turning them back.

Feeding

Septaria Porcellana is highly herbivorous compared to other snails. They can be fed daily with dried foods containing high amounts of plants or decayed vegetable matters. Their most preferred and favorite food sources are algae and biofilms. They are particularly suitable for aquariums with a dense algae population and growth. Rocks or decorative surfaces with algae growth provide the best food source for these snails. They can live without harming plants in the aquarium due to their algae consumption. They are also beneficial for the tank’s health by keeping the algae population under control.

Breeding

The reproduction of Septaria Porcellana is similar to that of other snails. This snail, which lives in freshwaters in its natural life, prefers brackish water or marine environments during the breeding period. Parent snails return to their natural habitat after spawning in brackish water environments. Young snails also need to be in brackish water conditions until they reach adulthood. On the other hand, they have also been reported to spawn and breed in freshwater. But, the reliability of these reports is doubtful. Due to the requirement of a brackish water environment, reproduction in an aquarium is so difficult.

In brief, these peaceful snails need a few simple parameters to live in an aquarium. First of all, the water quality should be high and the water must be clean. Second, they should be fed with algae, biofilm or dry food with a high plant content. If these conditions are met, it will live without any problem and add color and diversity to the aquarium.
