I added a decaf green tea bag to my betta Minion's tank for tannins. He's starting to show signs of fin rot so I'm hoping the tea will help a bit! His reactions to the tea bag were really cute so I thought I'd share :P
He likes to be close to the tea bag:
Here's a rather low-quality video of him interacting with the tea bag. He loops around it, sticks his body close to the tea bag, and even tries to chomp at the veins of tea-water seeping out from the bag. I think he rather enjoys it :)
Have you ever tried putting tea in your betta's tank? How did they react?
