When I first got Snowflake my pastel dragon delta I realized that he wasn't swimming that much and I thought he was just really stressed. Whenever he went up for air it seemed like he was really trying to swim up and than he'd just float down. So when I woke up today he was face down in the marbles and I thought he was dead. I moved his plant and he started moving so than I was watching him a couple minutes later and he was trying to get under the marbles and I've never had a betta do that. I did a 100% water change, took the marbles out because they were heavy and I didn't want him to get stuck under one, put light rocks in that I bought and put some salt in. When I put him in the temp bowl, I saw that his back fin had a red spot that looked like blood. I don't know what happened to him but it seems like part of his fin is clipped and his back is almost paralyzed. I feel horrible because he's probably in pain.
I put the water level down a lot so he doesn't have to struggle to swim up that high to get oxygen. Should I just keep putting salt in or should I add some JFC on top of the salt? I don't know what to do.
My sister and dad were like, well if he's going to die, he's going to die.
