Mushroom bent

[Capt502]

This toadstool mushroom is new. Will it straighten up? Also is the green corral one algae starting or something else?

It should - just give it a few days. I assume the tank is fairly new? It's most likely your rock just going through the natural process. I notice you already have some coralline starting, and various green and brown algae is are pretty common as the rock transitions to purple coralline.
