I've had Yuki for almost 2 months now. Until recently, he was perfectly healthy.
A couple of weeks ago, I cupped him to clean his 3G tank. When I put him back in, half his tail fin was gone! I kept an eye on it, and did 50% WCs every other day, with a full 100% WC on the 6th day to make sure he didn't get an infection where he nommed on his tail.
A couple of days ago, he started acting a little lethargic. He was still eating and pooping fine and his fin looked okay, so I just continued on with his WCs.
Today, he has red along the edge of his tail fin. (Is that blood or infection). He's even more lethargic, lying on the bottom of the tank breathing hard. He only moves to go to the top for a gulp of air, and then heads straight back down to the bottom again. And at times when he swims to the top, he zips around the tank a bit...like he's darting around.
I can't see anything else on him. He's white, so I can't see if there are white dots.
I want to start him on something. Since I have no idea what is going on, what type of salt would be a better all-around emergency treatment???
I should also mention that my last betta died after something similar started. But this betta is in a new tank, with a new heater, new thermometer, plants, etc. The only thing in common between my last betta and Yuki is the bottle of Prime and the container of NLS pellets.
Thanks for your help!!!!!!!

How has your betta fish's appearance changed? He's lethargic, lies on the bottom of the tank, won't eat, has red on the edge of his tail fin where he's chewed, occasionally darts around the tank, but only for a couple of seconds before he lies back down. I think his colour is slightly less white and has a tinge of...i don't know. he's just not has pure white as he was.
