See what hatches and let us know. Some corals can reproduce by sexual reproduction and those may be baby coral polyps.

Did you recently add anything to your tank?

[JoshOdphi]

i added some coral but i've had these eggcases if u wanna call em for a while now....even before i added the new coral..jus wondering if anyone knew what they were.....

I get those every so often they just stay like that until coraline grows over them. On rc they said it was a simple organism usually found in newer reefs. Mine came from when I added live rock to the tank.

[JoshOdphi]

u know if they're harmful / beneficial?

[kkiel02]

They are reef safe. They said that they will eventually starve themselves out I believe.

I think they are nerite snail eggs. I've got a bunch of nerite's in my tank and I see these often.

[JoshOdphi]

koo...thanks for the input....now that i think of it....went to the keys in may brought snails back...looked at caribbean nerite snails and looks exactly like the ones i collected...

[kkiel02]

Wow I stand corrected just googled nerite snail eggs and you are right. Well I feel kinda bad for scraping them off the glass now. LOL

lol I have tons of those all over the place.
I indeed found out they were Nerite Snail eggs.
Sometimes I scrape them off and sometimes I let them be.
Wonder if they ever grow up... or if they get eaten...
