I just joined, so I'm perusing the forum and came upon this topic. Didn't realize at first that it is sort of old. But just to join the conversation, I don't have any where near as much as some of you! Wow. But I have two mystery snails, a brown stripe and an ivory. They are about the size of golf balls. I also have two apple snails, one is also a brown stripe, about the size of a plum (its either a small apple or a large mystery) and a nice golden apple, about the size of a baseball.
I never realized until I got these guys how incredibly cool they are. They are so entertaining to watch and constantly amaze me. I enjoy watching them float up on the bubbles. And I can't understand how something as large and heavy as my golden, can perch on the end of a plant without even bending it towards the ground. I would love to have more, but even with 5 tanks either some are overstocked or, with my goldfish tank and my betta tank, just aren't compatible.
