I've been seeing a few of these little guys on the glass recently. They look like teeny tiny nassarius snails, but I was under the impression that they can't survive the larval stage in the hime aquarium. I do have tonga and atlantic nassarius snails in this tank. Is that what these are?
Not sure but I just happened to find 7 baby nassarius snails crawling on my glass today. I was about to scrape the glass clean and held off. This is about 3mm long zoomed way in. It looks just like the adults only way smaller.
