The King Koopa Nerite Snail (Neritina Juttingae)



Neritina Juttingae is also known as “The King Koopa Nerite Snail”, or “Algae Eating Nerite Snail” is a snail species that belongs to the Neritidae family. Neritina Juttingae was named in 1973 by Mienis H.K. This species, whose natural habitat is Borneo/Indonesia is an uncommon snail. For this reason, it is not well-known by aquarists. However, it has become interesting, especially with the different features in its shell structure. They also live in wildlife in brackish water environments. For this reason, they can be grown in both freshwater and brackish water aquariums.


Neritina Juttingae can reach 2,5-3,5 cm in length. It contains yellow, brown and cream colors in its shell. But, what makes the shell structure interesting are the small horns over it. These horns are rounded and turn black towards the ends. Also, there are white ring patterns exist in the shell structure. With these features, it is easy to distinguish this species from other snails.

Water Parameters

Temperature: 22-28 degree
pH: 6,5 – 8,0
Hardness: 2 – 12 dKH

Neritina Juttingae can tolerate a wide range of water pH values. But it prefers alkaline water with a pH level of 7,0 and above. According to the researches, it has been discovered that they can live longer in alkaline waters than in softer waters. Acidic waters cause crust erosion so, this situation poses a danger to the snail.


It is recommended that the tank size in which they are kept should be a minimum of 19 liters to grow healthy. Calcium supplements should be preferred to preserve the strength of the snail’s shell structure. Depending on environmental conditions and care, they can live up to 3-6 years. It is recommended to keep them in groups of 6 or more snails.


Neritina Juttingae grows healthy in well-established aquariums. Algae, biofilms, and decayed plant parts are the primary food source. Among them, it prefers to consume the algae most. For this reason, decorations or rocks that provide the algae growth in the aquarium will be the main feeding areas for this snail. They can also consume high-quality dry food with high plant content or vegetables. At this point, it should not be forgotten that Nerite snails may not always be good with dry foods. Therefore, if healthy growth is not observed with snails, the algae source should be increased.


Unfortunately, these snails are difficult to breed in a tropical aquarium like other Nerite snails. There is some information that they also spawn in freshwater aquariums. So, baby snails are born. However, this situation is so rare. In the wild, these snails prefer salty environments near the sea or brackish water to lay their eggs. This environment is also necessary for baby snails to reach adulthood. Thus, breeding these snails is a challenging task.

In summary, although Nerite snails are well known to aquarists, The King Koopa Nerite Snail is not yet commonly available in the hobby. With its horned shell structure and harmonious life, it gradually began to attract the attention of aquarists. It can be preferred by aquarists of all levels with its low care demands, no damage to the aquatic plants and adaptive capacity to a wide range of water parameters.
