I was wondering if anyone can help me on selecting a snail. I was looking to only get one that I will be able to see and eats brown algae. Is there are even a species out there that exist? I have a 29g tank with 11 Cardinal tetras.
If your tank isn't planted you could go with a gold mystery snail. After a time they do become huge, but generally you can take it back and get an exchange if it does.
