Things To Consider

How To Buy Healthy Gold Inca Snails

When you buy nerite snails, their shells should be free from cracks and signs of wear and tear. The snail should be active, stick to a hard surface, or moving about the tank. Do not buy nerite snails that are upside down or motionless. If you do buy a snail, make sure that the shell is not empty.

Live Plants

Planted aquariums provide extra food for the nerite snail to eat. Live aquarium plants shed plant matter that the snail may eat.


Nerite snails do not reproduce in freshwater aquariums. They need brackish water for reproduction to be successful. But, they do lay eggs. You may see Nerite snail eggs on hard surfaces like decorations, filters, or the heater. The baby snails won’t survive in freshwater as they need salt water to grow. All you have to do is scrape the eggs off the surface and remove them from the tank.
