I found a baby or what appeared to be a baby tulip snail in my tank. I know tulip snails eat other snails, and since there were no snails, only a few abalones in that tank, I let them be. 2 days later, I caught one of them munching on a zoa. I pulled the rock out to verify it, and low an behold, found another one on the rock right by it. These guys are tiny and unnoticible. Pic with a dew can for reference so you can see how small they are.
