    image.jpg Hi, ive had a little oranda for a couple of month and he is white & orange. Recently he has got some black streaks on his fin. The fins arent damaged as such but it has appeared quite quickly so I’m worried it is ammonia even though my tank ammonia tester says ‘safe’... i will add a pic... please give me your thoughts xx

    What type of test are you using? Do you have nitrite and nitrate?

    I have just ordered a kit to check. I have an ammonia test that sits in tank... i tested it on a chemical that has ammonia in so i know it works. Maybe nitrate/nitrites then? I only did a 50% water change this week too... is it poisoning? :(

    There's no way of knowing if it's toxin poisoning without a test kit.

    50% water change is high enough in one go. :)

    Could you walk us through your set up - tank size, filter make and model, whether or not you carried out a fishless cycle before getting the fish (fishless cycling the tank means adding a source of ammonia to the water and testing for ammonia and nitrite every day until the day when you add amonia, test both ammonia and nitrite 12-24 hours later, and BOTH are 0ppm. You'll then usually find a high nitrate reading). What additives you put into the water (dechlorinator, for example)

    In the meantime, to be on the safe side, I'd start carrying out daily water changes of 25%.

    If it is toxin poisoning, the daily water changes will keep the toxins sub-lethal, and a bottle of Seachem Prime would help by keeping ammonia and nitrite away from the fish.

    Just a caveat to LinznMilly's excellent post - don't add a whole bottle of Seachem Prime! Just dose once a day based on the recommended dose for your tank volume.
    (I'm sure you understood that perfectly well, but just in case!)

    Thanks all... i had the prime in my basket then read that it can kill the good bacteria or stop the cycle or something so i chickened out. The 240l (uk so dont know in gallons sorry) tank has been set up since August with weekly water changes using fluval tap conditoner and fluval good bactieria thingy. I was using test strips and my ammonia reader so now the liquid test kit is on its way I will try that and get back to you.
    I have a second tank set up and cycling to move half of the 6 fish in as I know they will grow.
    Thanks for your time... i will update you xxx

    Prime doesn't kill the beneficial bacteria. It converts free ammonia (NH3) into ammonium (NH4). The filter bacteria can still use it, but as ammonium, it's "locked" away from the fish, so the toxins don't harm them.

    In a fully cycled tank, it's just another dechloronator.

    They are, but they might skew the ammonia result.

    I have done a 40% water change again with hood bacteria & conditioner in. Will do the same tomoz and hopefully the test kit will have arrived by then. I will hold off on the ammonia remover until i have done a reading if you think that is best. Thanks for all the time you are taking with me x

    Hello again,
    So I got my liquid test kit and results are quite diff to the strips i had used:
    Here they are; don’t be cross at me.
    If you could let me know next best steps I would greatly appreciate it xx
    Thank you

    Ammonia = 0.25
    Nitrite =0.25
    Nitrate = 30
    PH= 7.5

    We won't be cross with you, but it does confirm that the black marks are likely to be ammonia and nitrite poisoning.

    Do a 50% water change now, to get those results down. Dose with Prime (once you get it) to keep the toxins away from the fish while the tank cycles. You'll need to carry out daily water changes until ammonia and nitrite are 0ppm. With 6 goldies in there, you'll have an uphill strughle, unless the filter is designed for tanks double the size of your own.

    Yes, if you have it already, use it.
