I just noticed this today, He has white fuzz on his fins. His edges are a bit worn out. I got him in a bigger tank last night. I am not sure how many gallons this one is as its a jar from walmart. It is not heated or filtered yet as I am still saving up for a larger tank. I do 100% changes every four days so the water stays clean.
I do understand I need a heater but for now my fish are right near the pipes for our heating in our apartment and I will have a heated larger split 10 gallon for my two boys. I know the proper temperature will help with his recovery.
My question is though how do I treat fin rot? What is the standard procedure for this problem?
Thanks for your time.
: the two pictures have been edited to try to maximize the look of the fins, I apoligize for the pictures but the camera didnt have a macro setting, very simple camera
