I setup a new 80l (20G) freshwater tank 3 days ago. The shipwreck ornament that was put in has a wooden mast. The wooden mast has green fur like algae growing around it already, approx. 6mm (1/4") all around the wood.
I am tempted to take the ornament out and remove the mast as best i can. Is this necessary or is it fine to leave it as it is? If I leave it, once the tank has cycled is there a fish that will eat this algae? It seems to be growing at an alarming rate.
