Very cool!!! Congrats!
There's a picture of it on TPT, but it's down now. I'll link to it when it comes back up.
EDIT: Found it
Nikolay, where did you get your sulawesi snails from?I had them at about 75 degrees. I didn't add any extra Calcium to the tank. Noting fancy so I can't give any pointers. Food was fish pellets, also nothing fancy.
Just saw one of the babies yesterday. Measures more than 1/4 inch and you can distinctly see the yellow spots.
