Hello everyone. I've had Elliot for almost four weeks now, and his appearance/behavior has changed within the last 3 days. It's been especially worse today. - Although he still swims around, he spends a little more time near the gravel than before. - There is a straight tear in his anal fin, and this evening I noticed what appeared to be early clamping--his caudal fin wasn't spreading out as much as it should. However, this problem went away after a water change. - His left ventral fin is very curled and ragged. - He will occasionally lean against/swim into plants and decorations--although I can't tell if this is resting behavior, or itching behavior Just checked my ammonia, and it was 0.25. I did a 50% water change, and working to get it to 0. I'm also going to pick up some aquarium salt, Indian almond leaves, and whatever medication you guys recommend. I just don't understand why this happened. His ammonia has never risen above 0.25. And as soon as it reaches that point, I make sure to do a water change. I also do a 25% every single day, regardless. I'm also using Prime, which I thought would help prevent this problem. Any tips? How should I continue with treatment? I have some sea salt in my kitchen (no iodine), should I add a bit to his water? Forgot to add: He is white, so I can't see any white marks that could indicate ick. And there is no discoloration at the end of his fins.
