If you want some variety in your Supershrimp tank, these are the animals for you. These particular snails are brackish water populations of Tarebia granifera or Melanoides tuberculata (you will get either one or the other species, or a mix). They have been living in brackish water for generations. They are so adjusted to higher salinity conditions that they can even be used in reef setups at full ocean salinity. As these snails are livebearing, they will also reproduce in your tank, although they won’t become a problem at all if you do not overfeed the tank. 10 snails are appropriate for tanks 1/2 gallon and larger. We have these snails in all of our Supershrimp breeding tanks.
