"Freshwater" Bumble Bee Nerite--7 years old and counting!
I just wanted to post something about freshwater/really brackish water nerite snails.
I see it all the time on the Google where the live expectancy is 1-2 years if people keep them in truly fresh water. And that it is several years more if they are kept in their natural state of brackish water.
I realize the term "freshwater" is for anything that is not marine water, but many people assume that it means they can be happily kept in true freshwater. In fact, when I first started keeping them, the fact that living in true freshwater significantly lowered their life expectancy was hardly ever mentioned back then. But now it is.
I am here on my soapbox to ask that you only keep them in brackish water, because lifespan is a good indicator of overall health and happiness.
As of this month, I have had a bumble bee nerite for at least 7 years, perhaps 8 as I had about a half dozen that I purchased over the course of a year. She (it is a she and still lays sterile eggs if moved into a new tank) has lived in brackish water from 1.005 spg to now 1.011 spg. I also had two other bumble bee nerites for just under 5 years that lived in the same space as she did. The others lived 2-4 years.
I know that they mow down algae like no other snail and don't breed in freshwater (because they aren't happy enough!), but please reconsider buying nerites the next time you are in the market for getting some more snails for your freshwater tank.
