Olive Nerite Snail (Neritina reclivata)

Description:

olive-nerite-neritina-reclivata

Olive Nerite snail where scientific name is Neritina reclivata is native to brackish water habitats in Florida and found throughout the Caribbean and Gulf of Mexico. This Nerite belongs to kingdom Animalia, Phylum Mollusca, genus Neritina and species N. reclivata.

Olive Nerite snails grow to a maximum size of 1,5 – 2,5 cm (0.5 to 1 inches) and usually, they do well in a tank with a minimum size of approximately 20-25 liters. These snails have a pretty rounded, smooth shell with a deep green color giving them their common name. Generally, the life span of Olive Nerite Snails is around 3-5 years. They are non-aggressive animals and easy to keep in the aquarium. It is not proper to keep them together with aggressive species like Loaches or Pufferfish as they will predate on Olive Nerites. Also, the tanks should have covers because these snails can escape from open-top tanks.

Water Parameters:

Temperature: 22-28°C
pH: 7,0 – 8,0
Hardness: 10-18 dGH

Maintaining suitable pH is necessary for the snails because if the pH gets lower than the prescribed value, it affects the snails harmfully. After all, acidic conditions dissolve the shells of snails made of calcium carbonate.

Feeding:

Olive Nerites are good algae eaters like most of the nerite snails. This species is often purchased to fight against algae and they eat many types of brown and green species of algae. As they originated from well-oxygenated waters, they do best in tanks with robust filtration and well aeration. They do not eat up any green plants unless they have plenty of algae in the tank. Especially, these snails are fond of green and brown algae. In addition, they can be fed with blanched vegetables, algae wafers, spirulina discs, pellet Foods, flake foods, and also calcareous material like cuttlebone, etc.

Breeding:

Olive nerite is an attractive snail that will not increase in numbers quickly in the aquariums, because of the required special conditions to breed. Olive Nerites will lay white egg capsules on tank decorations and plants in the home aquariums. However, these eggs will not develop in freshwater and they will not hatch. In the larval stage, these snails require high-end brackish or complete marine conditions to develop. The larvae can only survive in brackish water under favorable conditions as they need the saltwater’s calcium, minerals, and plankton to develop and build up their shells. Attempting to raise young snails would require a separate aquarium as the adult snails cannot tolerate these saltwater conditions.

Due to these snails only breed in brackish or marine waters, they are an ideal choice for freshwater aquarists who fear snail population explosions. In nature, the Olive Nerite ventures far upper parts of the rivers, often being found miles away from the sea. Olive Nerite snails migrate to lagoons or rivers for the breeding process where brackish conditions prevail. According to the latest theories, this unusual nerite is in the process of evolving from a marine to a purely freshwater creature basing on the latest researches and findings.
