I've been trying to figure out if what I have in my 5 gal Fluval Betta tank are limpets. They are so small - about the size of an Arial 14 pt. period in typeface reference. I don't know if they are really small snails, or they are limpets. In the morning, they are all over the glass, and I pick out at least 15 each morning, and many more during the day as I see them. The betta seems to have no interest in them. I tried dosing Excel every other day but that didn't seem to slow them down at all.
So, how small are baby pond snails compared to baby limpets?
In non printer terms - you might be able to fit three of my "specks" on an average sesame seed - maybe even five.
