So I recently got a tank setup and cycled for a new Betta Fish, The water is good and actually almost perfect besides hardness. However my Betta has seemed to have lost his appetite and his fins seemed to be clamped. I started treatment for constipation however he just seems to get worse. He has this goldish coloring to him since I got him, but now I’m worried it might be velvet. Any advice would be greatly appreciated. I’ve added pictures to show how he was originally and now.
