Tiny white spots on glass and overflow ?

[Hilltopreef90]

I’ve just noticed these tiny white dots appearing in my tank, I read they might be sporobid worms but they don’t appear the same spiral shape.
What might they be and are they harmful to my tank ? I just cleaned the glass and back of aquarium a few days ago and now it’s covered in tiny white spots (see photos)

Those look like baby snails to me. I get them on my glass

Do you have any nerite snails?
They look just like the nerite snail eggs that showed up continuously in my FOWLR before tear-down and relocation. Notice how some of them are burst open in your picture. I never did see surviving baby snails, though.

I agree... Not Spionid worms, Most likely baby snails. Hard to tell for sure in the pictures, but thats what it looks like.

I never had any babies survive either

Are they at all harmful to my tank or corals

Not at all!! In fact, they are quite desirable.

They're easy to scrape off with credit cards, I just let it go in the sump though, last time I scraped was 3mo ago. They can be hard on pumps and impellers so check and maintain your equipment.

What makes them desirable? Just curious. I wondered if the fish eat them because they always disappear and my snail population isn’t growing.

Haha.. well, they are desirable if they can make it past the "fish food" phase. As I said, I have never had them reach adulthood either.

I was thinking spirobid worms but there is more to this. Are you able to scrape with edge of an old credit card?

 

[mindme]

hard for me to tell in the pictures. If it looks like a snail that is stationary and stuck to things, then it's the spirobid.

If you have nerite snails, they will lay eggs on the glass. They will never hatch/survive, they only hatch in brackish water.

Either way, you can just scrap them off if you want.

Ok.. this is what my whole tank looks like.. even growing on the base of some corals.. possibly causing some hammers to close and die. They are hard... have to use a metal scraper.. and there are thousands. Also in overflow. do people still think they are snails???
