Iāve had my Betta since February and soon after he developed brown patches on his back. I figured it was from stress and he was fine after a water change but still discolored. Itās April now and heās gotten progressively worse. He currently has fin/tail rot and patches on his sides have shown up within the past week. Iāve medicated him daily since for the rot and (what I believe are) ulcers. Heās still eating but is constantly too dwelling. Heās clearly having a hard time breathing and his gills look inflamed. Iāve looked up Columnaris and Velvet, which seem to be the only contenders. Although, theyāre deadly within a week. I feel like Iām just waiting for him to die. The picture where he looks green is when his whole tail fell off within 8 hours. What do you guys think?
