What are the fish and snails you have in the tank?

I do not have any fish at the moment., only a Mexican snail and a starfish.

Turbo snails eggs look like a squiggle line of gelatinous dots.

A search indicates a possible deposit of Starfish eggs. I saw a couple pics which looked very much like your pic.

What type of starfish?

Is it soft ?
It could be a macro algae turning white .
Was it on the rock or did it just grow?

I am afraid to touch it, therefore I do not know if they are soft. They look hard and stiff. They show no movement. It just grew on the rock from nowhere.

It looks like Neomeris sp. "spindle weed" bleached out . Do you know your Ca level ?
First picture in link ,but your is white.
