I’ve had my baby betta boy, Shimmer, for a week now. Since he’s been put in his new home, he swims around like crazy every day! He always seems full of energy and loves food lol. He swims back and forth, swimming through leaves and plants, up and down the glass. He’s a crazy guy. But I noticed his fins have changed over this week. I attached a picture of when I first got him and how he looks now. I’m thinking it’s tail biting or from him swimming so fast and crazy? It certainly doesn’t look like fin rot. Any advice? I also have a banana plant and Indian almond leaves.
