What Does This Mean, snails?

1187 Views 8 Replies 7 Participants Last post by  James From Cali
I have snails (mostly MTS) in my two tanks and have observed interesting behaviors. From time to time, sometimes after water changes, I see my snails out on the glass by masses. What does this mean when the snails are out of the substrate and on the glass? Does this have something to do with the water quality? Can this possibly mean lack of O2 in the water or any other water issues? Just wondering ...

No one knows what it means when the snails come out to the open from the substrate?
The literature would suggest that snails will begin climbing upwards on the glass when water quality is poor. Based on my own personal experience, I am not too convinced of this. I don't have MTS but pond and some other types of ugly snails(I am unsure of type) that do this all the time. I don't believe this indicates a water quality issue. In my case, if there was a water quality issue, my Amano Shrimp and Otocat, which are the most sensitive to water quality would be dead.

In your case, I would suggest testing your aquarium water just to be safe. Many aquarium shops test the water for free. If your ammonia levels are fine, I would not worry too much about it. The only other thing that snails need is sufficient calcium. I have read about calcium deficiencies will cause snails to die amass. Their shells turn all white, indicating a calcium deficiency or in some cases too low a PH.
