So I am still struggling with my guy Henry the betta. He is my only fish with live plants. I have 5 tanks with 5 bettas. He is my little sickly I guess. All my other bettas have silk plants. I bought the live hoping it would help him heal. When I first started treating his rot fin I started out with doing every day half water changes to his heated 5.5 gal tank. When that didnt help any I started to use betta fix. Then bought almond leaves. Then bought aquarium salt and started giving him salt baths every day. When that didnt help just stressed him I came to fishlore for advice. I purchased furan 2 for rot fin it didnt help I removed filter and everything just as directed. It turnt my water green which was removed wen I turnt my filter on after the treatment failed. I then started to give up then I bought fungal powder for fish didnt help either just discolored the water. And lastly here I am still struggling with poor Henry months later. I just got some new medicine I found online for marine and fresh called kanaplex. Just started that treatment today fingers crossed it works. Any advice on any thing else I can purchased that helped someone with persistent rot fin? Is there a method I can use to make the kanaplex work full ability. Is there a reason I can't get rid of rot fin after all those medicines for the fish? I know rot dum can cause damage to the fins forever but I can see his fins have black tips and the disease is still eating his fin away no matter what I do. How long should I use kanaplex it says remove filter and dose every 2 days doesn't say when to stop dosing? I'm sure if every two days u put the kanaplex in without water changes or filter itll over dose the fish right? So should kanaplex only be used every 2 days for one week then u should make a water change n continue if no improvement has been seen? Should I be using salt baths with the kanaplex since this rot fin is hard to get rid of?
