Hi,
Does anyone know what causes the green-ish spot on this type of Nerite?
Thanks!

It's just where the outer surface of the shell has eroded. All my snails have areas like that on their shells, with the 8 1/2 year old zebra nerite having a large amount of eroded shell. Judging by my nerites, it doesn't seem to affect them, just makes them look not quite perfect.

Yes. I bought a zebra nerite and one of those red ones with black markings that you see called red onion or tyre track in July 2011.

This is a photo I took of the zebra nerite in October 2018, as you can see it's badly eroded but it's still crawling round the tank 15 months later. The white band is quite hard it's just where the surface layer has come off.
The second photo is the other snail I bought in 2011, the photo was taken in April 2016.

I really don't mind so much how it looks.
What causes the erosion?

Wear and tear; pH less than 7.0; soft water. They all contribute. If your snail is recently bought, I would also add rough handling/tank cleaning by the shop to the list.

I wish the LFS sold more colorful ones like your, I am happy with them for what they do. I miss the color the Golden Mystery Snails add to the tank but not the damage they did to my plants. I now have several ramshorn snails in my shrimp tank they are hitch hikers. They also are a shade of brown.

You have a tiger nerite snail. It’s just a different variation of the many out there.

My LFS carry’s zebra Nerite snails, golden Nerite snails, tiger Nerite snails, horned Nerite snails, etc. They have a pretty big selection. Nerites are by far my most favorite snail. :)

I do have a question though, some of BRH snails are starting to look like this:

It’s almost as if other smaller snails are started to eat it’s shell? I don’t know for sure though. Should I be worried?

Where I am I have a Petco that seems to only sell apple and mystery snails and the LFS that sells apple/mystery and brown nerites, I have 7 in my 55 gallon and 2 in my 30 gallon. So I guess I will have to buy online to get something different.

I never buy snails from PetCo or PetSmart, they always seem unhealthy. You could try buying Nerite online, but I don’t really recommend it. Try looking around for more LFS’s.

Unfortunately there are none close by, we use to have 3 LFS but no more. The next closest store is a Petsmart and I did not like the look of their fish, they seemed stressed and too many sick fish in their tanks. They did have a nice selection of tanks and supplies. I would have to travel over an hour away to the closest LFS. :(
