Hey, wondered if anyone knows what this strange green/yellow sponge like growth is that i aquired with some live rock. It is also wrapped around my palys and wonder if its that causing them not to open up?

If your PO4 is up or it’s a newer tank. Usally sponges feed on phosphate.
Usually pineapple sponges will blow up till it’s leveled. When you touch will it break up or has structure?

Hello. And thanks for reply, i forgot to add phosphate results, they are 0, this has structure and is kind of springy, also as its wrapped around palys which contain palytoxin i dont want to play with it toi much. This came from another tank and has been in mine about a week now (it didnt grow in my tank) thanks again mate!
Also my tank is about 6 weeks old but fully cycled.
