What is this please?

[Nyx101]

Could be a rock but I have nothing else in the aquarium that resembles this. Could this be clownfish or shrimp eggs?

Can you get a better pic. Clownfish aren’t flat and shrimp eggs are carried by the shrimp.

 

[Nyx101]

I’ll wait for the hermit to move... but I’m relieved. Only have clownfish and shrimp couples. Could it be some kind of pests spawning or hermits? Don’t care to disturb the tank if it’s nothing.

Looks like plastic or some other foreign debris.

Is it the hard part on a snail the were the mouth is? That a hermit ate and that’s the only think left. I have found some of those in my tank

Doesnt look like an operculum....
