Whats this on my rock

[begginersluck]

I've just discovered some strange looking egg like things on one of my rocks. I've not checked any other rocks yet but I don't like the look of these. They're all over the underneath of the rock.

I don't know if its normal but the past few times of taking my hand out of my tank my arm starts to get very tingly and itchy. Is this a sign of anything or just the salt irritating my skin?

Iam not too sure because it can be anything . If it was a new live rock you just added you should probably take it out and quarantine it and watch because it can be shrimp egg or something else. If it is a rock you had for a while like a couple of months. Look around the tank more carefully there should be something laying the eggs unless you have other invertebrates inside the tank or paired fishes

iPhones take the worse picture under led lights.

It's hard to describe them but they look like and egg shape, some of them just have an open hole and other have something coming out of the hole looks like a feather or something but they're not feather dusters. I don't think.

Sponges.

There loads of them and they're tiny. Is that what sponges look like?

 

[Voshon247]

Could be a type of sponge

Those are pineapple sponges.

I've heard moorish idols are partial to those?
