I purchased a Betta abt 7 months ago. His home: 5 gal heated filtered tank, 2 live plants & rocks substrate. 100% water changes abt every month. Roughly 1-1/2 weeks ago, he started acted funny. He would come up to eat but not eat, or spit it out. Then, no interest in food & started laying down on the bottom with his body half flopped over & VERY pale. I thought he was constipated. Now he is in a smaller container with epsom salt that floats in his tank. He has been in 1 quart of epsom salt water (daily changes) for 6 full days now with no improvement, breathing a little heavy, no eating or pooping. I saw a silver shiny spot near his face tonight. His face below his mouth has become gray, like an older dogs. His face being gray has been there for a over a month. He used to be quite feisty and flare alot, even at his own reflection where the filter sits. He has blown his fins several times which have not "healed". I do not see his scales sticking out. Is there any saving this poor guy?
