I like my tiger nerite, but I have to say they have sloppy poops and don't turn the substrate. Plus they can lay eggs which sometimes can look unappealing.

So, I am back to considering trumpet snails. But I am at a loss what the difference between the Tarebia granifera or Melanoides tuberculata when it comes to reproduction or behavior is. I do like the shorter shells of the Tarebia granifera, but is it worse or better than the other one? Anyone have both and can explain them better for me?

Neither. Even though I have them in my tanks I wish I never put them in there to begin with. Some tanks the population has gotten out of control to a degree. I guess you can keep an eye out for the population.
