Zoo Med Betta Mopani Wood
Zoo Med’s Betta Mopani Wood is a natural wood item designed to mimic the water conditions Bettas experience in the wild. When placed in the tank, it slowly releases tannins, giving the water a light to dark brown tint and lowering the pH level. Bettas naturally live in environments with decaying plant material and slightly acidic water, so this wood helps replicate those natural conditions.
If the water turns too dark or the tint is not to your preference, the Mopani wood can be removed and soaked in clean water. Replace the water regularly until the color fades from dark brown to light brown or clears completely.

The Mopani wood worked well in my Betta tank. After a few days, the water turned a light brown, which I liked. I changed the water a few times and it faded to a clear color. My Betta seems more active and the water feels more natural.

I added the wood and noticed the water color changed gradually. It lowered the pH slightly, which I think is good for my Betta. I had to soak it a couple of times to get the color to lighten. Overall, it’s a helpful addition.

The wood is easy to use and gives a natural look to the tank. The water tint is subtle and the pH drop is gentle. I appreciate that it mimics the wild environment my Betta would naturally live in.
