White spots on back wall?

[JPR1212]

Hello everyone!

so recently I’ve been seeing this white spots pop up on the back wall. I’m trying to figure out what they are. I started seeing Them on there like 1.5 weeks ago. I don’t see anything that seems to be “living” on them. They seem to be hard and can be scraped off the back wall. However, I recently started seeing coralline on my rocks and not sure if this is just the start of coralline growing on the back wall. Never seen it start happening like this in any of my other tanks so I’m not sure what it is. Any help would be great! Thanks!

Baby snails?

I can’t tell without a closer picture but google search spirorbid worms and see if that’s what they are.

Hey! It doesn’t seem to be the spirorbid worms. The ones in my tank are almost perfectly circular with no visible spiral and white. They do have a 3d aspect to them though as they do stick up off the glass just a little.

Have any nerite snails?

Baby snails?

Honestly not sure. I’d imagine if they were eggs they’d be soft and squishy. And if they already hatched you’d be able to see them slowly move around. Whatever I have is on the back glass and seems calcified on there.

Tiny tube worms?

Have any nerite snails?

I believe I do. Not 100% sure though. I know for a fact I have astrea snails, turbo snails, nassarius snails. There is one more kind of snail in there. I forgot the name but it’s in this picture. I want to say it’s a nerite snail but like I said not sure.

Nerite snail eggs often get said to look like sesame seeds.

Yep, I get them all over the place. I also get really small, like sand sized grains of white dots on my back wall as well.
