Last one... what is this?

Purple is coraline...but what is the orange? It has a texture...reminds me of snakeskin.

1) Does it like/need light?
2) Does it like/need current?
3) Does it need feeding?

Coraline can come in different colors depending on the lighting.

Looks like a sponge to me, could be coraline though, is it hard?

What is this?

It is hard...like coraline...yet textured, like it is made up of a collection of hexagons laid out flat together.

Perhaps coraline that has overgrown a dead coral?? More than likely it is another form of coraline.
