At this point, it looks like the beginning of ich, but there are a few pathogens that start out that. Whether it's ich or a paracite. Either way, recommend a treatment that would cover both without harming the biological filtration. It's Tetra Lifeguard. Follow package directions and the fish and tank will be free of both types of pathogens. And don't let any other post talk you into bettafix or Melafix. They are as about as useful as KoolAid.Lino-Raye said:So this white spot has popped up on my betta and I have no idea what it is or how to treat it. Can anyone please help me?
