I only just now read that you should only add a nerite snail to your tank if you have algae growing. There has never been any visible algae on my tank. I have had a nerite for several months and have never fed him. Now I'm worried the little guy is starving! Do I need to feed him?
Since we're on the topic, I have four (not sure!) baby ramshorns that are growing quickly. I assume they are getting enough to eat, as they have doubled in size in just a few months. I'm guessing they don't need any feeding?
