So I think I've fallen in love. I currently have 2 Nirites Snails and I love them. I never thought I would, but they are so interesting to watch. Since then, I've been wanting to get more snails. Current tank is 29 gallons. The two I currently have do great! I've been thinking of adding more snails but need help! Today I looked at Mystery Snails and can't seem to find the perfect one. Most places seem to have slim pickings or dead ones. However, I saw some amazing Trapdoor Snails. They were super cool. Quite large too. About golf ball size. Can Trapdoor Snails live in aquariums? I've read that they are only plant eaters when food isnt available. Would they cause issues with my current snails? Should I stick with Mystery Snails instead? If so, how many mystery snails would be okay without bothering my 2 Nirites Snails? Thanks!!!
