I just saw this tiny thing moving up the glass eating the diatoms in my 5g quarantine tank (where the 3 baby Platys live). It looks like a baby snail. What's weird is the plants that are in there came from my 75g tank. However, I've never seen any in that tank where my 6 Dojos and 5 Platys live. Maybe they ate them? Or maybe they haven't shown themselves yet? Another new experience in my Fishkeeping journey!
