Strange Dots

Eggs from something else, maybe? Not mts eggs.

Probably baby MTS. Hard to tell from the pics but MTS do not lay eggs they are live bearers. The babies look like little tan versions of the adults with a conical shell.

Could also be bladder snails (physid) snails or pond snails, whatever people like to call them. They are shaped more like a ball rather than a cone & they hitch hike on plants a lot but they are harmless. They do lay egg clusters that look like little globs of clear jelly. If you have both physid & MTS in the same tank one of the two will out compete the other. In my experience usually the MTS out compete the bladder snails.

i think they are to small to be eggs.but i think someone will know whose eggs they are if you tell us EVERYTHING that you have in the tank.

I have tons of MTS and have never seen MTS eggs. They seem to multiply by magic. The spots don't look like MTS babies, they are too big, white and round. I had a nerite snail once that would lay white round eggs everywhere. That might be it. If it's nerite eggs they probably won't hatch, I think they need brackish water for that. My other guess might be baby pond snails from the hornwort.

Do the spots move?

Probably Nerite snail eggs, only the female lays eggs.
