can we add snails to aquarium ? what does they do and are they friendly

hi! jusk like any force, snail can be used for good and for evil. they have a reputation of rapidly devouring plants, multiplying like crazy and turning aquarium into an unsightly mass of creeping grey slime, but his only the dark side of the snails. when properly managed, snails can actually do a lot of good in your aquarium. if you introduce factors that balance thier numbers, they will settle in thier designated ecological niche in your aquarium and carry out the same beneficial work that they do on the wild...oh by the way the another problem with snail in aquarium is, because they are scavenger they eat eggs of fish..hope this help..

Snails are good if you have a puffer fish or a tiger fish to balance the eco system in your tank. Actually, snails can mess up your aquarium by eating plants and making your aquarium dirty, they also can reproduce rapidly and make your tank unsightly just like what Bart said

Perhaps this is not a good idea. The snails grow so fast and they grow more and more. They eat the weeds which they are very nice decoration for your aquarium. The fish need the plants, such as the weeds. It makes them healthy. I love China
