    Hi guys

    Just got home now I noticed that my kole tang lying dead at the bottom of the tank. He can only be dead for a couple of hours maybe just over two..
    Do I need to do a water change? I've taken him out of the tank as soon as I noticed he was dead. I'm worried about the lives of my other LS.
    He was a new addition, wasn't eating much..

    Can't think of anything else that could have killed him.

    Sorry to hear bud :(

    set skimmer to skim 'wetter'

    check Ph and dose alkalinity if possible to prevent the ammonia(if any) lowering the Ph

    Other livestock should be fine but consider keeping lights off tomorro until nitrates decrease to prevent an algae bloom, also what is the other LS?

    try to determine the cause of death, if it could be anything other than not eating(whitespot etc)

    dead fish take a good couple of hours to start decaying

    Thx for the advice guys. All other lf look healthy and are eating well. There doesn't seem to be any fish with whitespot. Ph seems a little low will dose. All other tests seem to be fine. Should I skip a feeding day?
    How would one tell if a tank is suffering from whitespot?

    Depends how and what you feed, just keep an eye on the nitrates and keep minimal lighting until they drop.

    If they don't drop, consider a waterchange or something the more experienced members recommend.

    What other livestock is in the tank? Whitespot affects certain fishes, check fish to see if they have white dots on their bodies. I don't really know alot about whitespot and i think the more experienced members are asleep at the moment :)

    as I said im not expert with whitespot but I think the yellow tang is the only one at risk of whitespot.....i think.....

    Just take a good look at home and observe.

    The other members will help in the morning but remember to keep an eye on those nitrates, 50ppm is fairly high, its not high enough to cause other fish to start dying but its far from ideal :p algae would love it

    I hope all goes well :)

    Unless your skimmer normal waste increased, then do not worry about a water change. If the skimmer did overreact and produced a lot more skimate, then yeah a water change might be a good thing. But now, 8 hours later the skimmer would have taken out whatever released by the dead fish.

    What was the size of the fish, compared to the system. Is a small 5cm fish in a 500L system, you would hardly notice a increase in any water parameter, depending on how good your clean up crew is.

    At No3- 50ppm I have seen stress in the fish of my previous tank.
    Redsea has a product no3po4x that you can use to lower your NO3.
    I used this product in the past with great success, just be warned that you need to use this product to exact specifications. It removes O2 from your tank, so add a airstone.

    Thx for the advice guys.. I've retested the water No3 hasn't dropped yet. The tang was about 6,5 cm in a 250l system. Will pick up this redsea product I suppose it will come in handy in emergencies..
    I'm planning a water change tmw, atleast 35litres.. I'm sure that will lower the nitrates.

    Don't know if this is related to the kole tang dying, but my longnosed hawkfish has stopped eating.
    Any ideas as to why? What can I do to entice him to eat again. I've noticed that when feed frozen foods he now swims up has a look around without eating anything. I really really dont want to loose another fish...
