Azalea root (large)

Azalea root is sometimes known as as spider wood when offered for sale.  It floats so needs soaking but doesn’t give off tannins or change the pH. It might create a bloom or biofilm/fungal growth but not always. Some sellers bake it before shipping to treat it for use in the aquarium.

It’s an attractive golden brown colour, and as the nickname of spider wood suggests, it’s quite a tangly looking wood.  This makes it a visually interesting addition, as well as offering hiding places for smaller fish.
