What are these?

[erniro]

Hi guys, I'm new to all of this. I recently setup my 75 gallon and added 50 pounds of dry rock and 50 pounds of live rock. Its cycling right now, but I'm wondering what these are? They're not looking as good as they did last week. I'm wondering if lighting and/or feeding them would help? Or maybe something else? Thanks

They look like they have filter opening in them, so I want to say they are both sponges. Not sure what kind, but if they are, I'm jealous. I just have boring white and black sponges.

Yep.. looks like some interesting sponges.
Where did the rock come from?

I got the live rock from Tampa Bay Saltwater. Pretty awesome stuff.
