We have 2 left, one is striped and the other is black.
Neritina turrita are the most wonderful snails and for those of you not familiar with them, they are excellent algae eaters. They have been in the hobby for many years and are great workers - particularly good for cleaning rocks and glass. Although more common in the marine side of the hobby, they are very adaptable and hence become popular in the freshwater side.
Found within the Pacific and Caribbean Oceans, they've come quite a distance.
They do not eat plants which is why they are so wonderful and their shells are extremely attractive. The picture shows a type available but patterns will vary from snail to snail as you can imagine :)
Most suited to aquariums without CO2 - an acidic environment can erode their shells and cause them to die. If you have loaches, it's best not to keep Nerites with them. Nerites grow to a maximum of 2.5cm in length. It's important to keep a close eye on their food as once their algae runs out, they will need supplements. However bare in mind they are slow, it's best to put pellets or algae wafers down at night time when there is less competition. Any deterioration on their shell needs addressing immediately and they will need more calcium in their diet and a pH neutral or above.
Note: Nerites have to be sent via Express Delivery.
Acclimatisation: Very little is needed. Simply gently place your snail into your tank (avoid dropping them) and make sure they are upright. After a few hours they should start to move.
