Like the title says need some help identifying what type of snail this is. I added some frogbit to my tank about a month ago that had some snails on it but I went over one by one getting rid of any snails I saw even the tiniest of snails. This is the first time I see one in my tank luckily I’ve only seen that one and it looks kinda big. I do have a mystery snail that I added about 2 weeks ago but I haven’t seen any egg sacs. Would it be normal to just now a moth after start to see them?
