Ok, so about a month ago, I purchased an amazon sword to go in my 2.5 gallon tank. It receives enough light, and I give it fertilizer after each wc. A week after putting Flapjack in his new tank, he got fin rot. He is still recuperating from it, but getting much better. Anyway, because of that, I completely clean his tank every 4-5 days, and of course I have to take everything out of the tank...so now my amazon sword is dying, and I would like to know how those of you with live plants handle water changes in your tank?
I don't know if I should just take it out all together( I really don't want to, I love the look of live plants), or just keep trying? I know you can clean with a gravel vac, but since he is still dealing with fin rot, I have to clean his tank completely...

So any suggestions?
