    Exclamation Why are all of my discus breathing at the surface?


    0 Not allowed!
    Hi,

    All of my 11 discus are at the surface and breathing air.
    I checked the following:
    pH= 6.4/6.5
    Nitrite=0
    ammonia=0
    nitrate =0

    temp= 28.7 Deg C.

    I did a water change yesterday with aged tap water.

    Why are they doing this? Last night, they were swimming around fine.

    What seems to be the problem? I need all the help I can get.

    Thanks,
    Sue

    Do you have an airstone in the tank? it sounds as if they are having trouble breathing. I would pump oxygen in there ASAP

    yep, put in a airstone

    my 90g had a corner box filter and a HOB temporarily after my resun canister broke and after i got the fluval FX5, i submerged the FX5 output and they were all gasping for air. i put in a powerhead with a aerator and all is good

    Yup, you need to get some surface movement going on in there. The warm temperature of the water lowers the oxygen concentration in it and thus the surface nees to be a bit more turbulent to allow for better gas exchange.

    How big is your tank?

    11 discus in one tank is a heavy bioload, you need to provide surface agitation.. Oxygen deprivation could be the problem but I am willing to bet it is as much carbon dioxide build up.

    Better than any airstone, is surface agitation, point ythe outflow from your filter towards the surface so the water, this allows not only oxygen to enter the water, but also carbon dioxide to exit the water.

    I had airstones, and in the end removed them, they were noisy and not necessary. If you go to any good local fish shop you will see very few airstones, but you will see the filters stirring the surafce of the water in some way. It doesn't need to splash, it only needs to agitate the surface.

    Also, 28.7 degrees.. is that the recommended temp for discus? it sounds pretty hot, but then I dont know much about discus.
