Sponge and eggs - ID Needed

[AddiV]

Hi All

My new tank is cycling with LR for about 2 weeks now. I have noticed this odd sponge looking growth on one of the rocks. An ID would be appreciated :

My second query relates to what looks like eggs stuck to one of the rocks :

Thanks

The 1st one could be Tethya...I could be wrong as the colour isn't "Orange"
what is this sponge thingy? - Marine Aquariums of South Africa
Sponges

Have a Look thru this Site...
Sponges (scroll to the top)

The 2nd one I can't really make out...actually looks like the round substrate you get......is it multiplying..?

@RiaanP ...could the 2nd picture be the same as the Sponges you just posted on this Thread...

Does not look like nerita eggs.

They are not all the same size. And I doubt if you got that many snails in your system

More likely sponges

no
Nerita eggs are laid independently from each other. Normally a gap between the of a few millimetres if not even more than 10mm. They are glued to the surface, normally tank glass but any smooth surface will do. And definitely not on a string.
