As shown in the clip my betta fish has barely been swimming for the last few weeks, he constantly has to rest and takes rapid or slow breaths that are always shallow. He can swim for short periods of time, however when he does his tail also droops. He’s also been laying on the floor of his tank while breathing like this and i’m just not sure what to do or how to help him. His tank is currently being covered to reduce stress, it is heated and has had the water changed twice since this started. The only thing that I could tell was wrong was the hardness of his water if you have any idea what to do or how to help please let me know
