    I've had goldfish with rot before and it was much worse than this. But I'm still not sure why my ranchu's fins aren't as smooth on the edges as they once were. It's a 35 gallon tank that I'm currently in the process of buying a new light for. The PH isn't harmful, my water has no nitrates, nitrites, or ammonia. I also change a third nearly each week. Any advice?

    What is Ammonia Level?
    What is Nitrite Level?
    What is Nitrate level?
    What is Ph Level, Tank (If possible, KH, GH)?
    What is Ph Level, Tap (If possible, KH, GH)?
    What is the brand of test-kit used(strips or drops)?
    What is your water temperature?
    What is the size of the tank (how many gals.) and how long has it been set up?
    What is the name and size of the filter(s)?
    Is there any substrate in the tank? If so how deep? and what kind (sand, gravel)?
    How often do you change the water and how much?
    How many fish in the tank and their size?
    Do you use water conditioner(if so, what kind)?
    What do you feed your fish and how often?
    Is there any new fish/plant added to the tank? if so how long is the quarantine period?
    Is there any medications added to the tank?
    Describe the problems you are seeing: example grains of salt on body, bloddy streaks, frayed fins, fungus, staying at bottom, not eating, etc?

    Please answer these questions, until then change at least 50% twice per week or 80% weekly, vacuum your gravel if you have any
    and take a picture of the fish so we can see what is going on

    Fin fraying can result from mechanical damage. Please show a full tank photo so we can look for possible problems. Sometimes it can be a response to stress. I once had all of the fish that I moved from one stock tank to another exhibit frayed fins. They all healed up within a couple of weeks.
