Solve a mystery !

[Wug]

Hi everyone, can anybody solve this ?
When feeding the fish in my reef tank this morning I found something on the side of the glass that I don't recognise, it has uniformed pattern and has obviously been deposited by something, but what ? See picture

It is probably eggs from some invertebrate - but from whom ......

Sincerely Lasse

Must admit that is my thought but would like to know which one

I think they're snail eggs.

Hope so, save me buying more ! Lol

If you have any fish, they probably won't last long. Mine love to pick them off the glass.

Yes there are fish, but so far shown no interest, the reason I asked if anybody knows is if it is worth protecting them

Assuming I'm right, they're probably trochus, cerith, or nassarius eggs. I began noticing them after adding snails for the first time. My money is on Cerith. Would be interesting to hear if they're still there in a week. Mine never last more than a few days, and I seriously doubt any of them get around to hatching

I have all of those, cerith being the newest. I have a net I can put over them. Maybe worth a try.

It’s a sign that winter is coming

Solved it!

Yup. Snail eggs. IMHO not worth the trouble of trying to save. Depending on the species, some may make it. Most will not - they'll be fresh seafood for the other creatures in the tank. But never fear - there will be an endless supply in the foreseeable future. It's what snails do (for fun?)
