Weird Patterns On Glass of Tank?

[therealkilo]

So in a couple places in my tank I have some odd looking items on the glass. What are these? Should I remove? Should I be concerned?

Thanks in advance!

snail eggs?

 

[therealkilo]

I do have numerous types of snails. Is this a good thing? Leave them?

 

[Dkuhlmann]

Yep, just leave them in the off chance you might get lucky to get babies. Usually they end up as fish food. The only once I clean are on the front glass

 

[therealkilo]

Sounds good. I will let them be. I am sure someone will eat them then. Or maybe I get baby snails! Thanks guys!

Could be nudibranch eggs.

 

[Reefaholic1978]

Definitely snail eggs.

 

[chimmike]

fish food.

What kind of snails do you have exactly? Some snails are broadcast spawners while others do lay eggs, but this doesn't look like your run of the mill Cerith, Nerite etc egg sack IMO. Like mentioned above, it could be something more sinister.

 

[therealkilo]

For snails I have:
5 Margarita Turbo Snail
5 Turbo/Astrea Snail
5 Cerith Snail

Other guys:
5 Red Leg Hermit Crab
5 Blue Leg Hermit Crab
2 Emerald Crab
1 Peppermint Shrimp
4 Cleaner Clam
Pair of clowns

Thoughts?

The Astrea, Margarita & the Turbo snails are all broadcast spawners I believe and those don't look like Cerith snail eggs to me either. It's not the clowns or the peppermint shrimp. I don't know very much about the clam or the crabs reproduction cycle, but the fact that the egg sack is up on the glass like that then I would have to say no to these as well. It's something else IMO.
Maybe somebody else with more experience with this stuff will chime in here soon though.
