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 matter and slightly acidic water, so this wood helps replicate those conditions.
If the water turns too dark or the tint is not preferred, the Mopani wood can be removed and soaked in clean water. Replace the water regularly until the color shifts 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 now it’s clear. My Betta seems more active and the water feels more natural.

I noticed a slight color change after placing the wood in the tank. It took about 5 days to reach a light brown tint. I rinsed it a few times and it stabilized. My Betta hasn’t shown any signs of stress.

The wood is easy to use and helps create a more natural environment. The pH dropped slightly, which I think is good for my Betta. I plan to keep it in the tank long-term.
