A lot of fish keepers want to diversify their aquariums, and for that purpose, they add small snails into the tanks. Snails are a great species because they not only diversify your tank but also help you clean it as they are natural cleaners of the fish habitats. Freshwater snail species live in freshwater habitats around the world. The major food source that these snails consume is the algae that grow inside the rivers, streams, lakes, canals, and ponds. When it comes to keeping the snails in the tank, there is a divide between aquarium owners, as some like them and some want them out as soon as possible.

This is because these small crustaceans help clean the tanks, which is a good thing but these snails can grow very quickly in numbers. These crustaceans do not need a partner to breed, because they are hermaphrodites. Each snail has both male and female sex organs, which allows it to reproduce by itself. This causes a huge population burst, and they can overtake your entire tank if you are not careful in dealing with them.  For that reason, a lot of fish keepers want them out of their tanks. Apart from kicking an entire generation of snails out of your tank, other measures can help you control the population of snails inside your tank. Here is a list of these measures that can help you deal with the snail eggs in your tank.

Other solutions include finding the snail eggs, getting them out of the tank, and putting them in any other tank where the snail egg eater fish are present. When you put those eggs in the egg eater fish’s tank, they will eat those eggs and hatchlings.
