  1. Default Cardinal tetra issues


    0 Not allowed!
    I have a 40g tank, it has been up and running for 6 or 7 months. So I decided I wanted some cardinal tetra. I bought some and put them in the tank. With in a few days they were all dead.I have probably been through about 15 cardinal tetra and not one has live. They all keep dying. I have other fish in the tank like guppies, platy’s,Zebra danio and a Red and Blue tetra. I had no problems with them ,it was just the cardinal tetra. I had my water tested and the nitrates were a little high but I got that under control. So I need a little help here with the cardinal tetra. I would like to have some in my tank but not if they keep on dying.

    Are you acclimating the tetras vs. just dumping them in?

    1x 220 gallon, 2x55 gallon, 1x40 gallon long, 1x29 gallon, 1x20 gallon long, 1x5.5 gallon, 1x2 gallon

    Question

    What is the nitrAte level? Since the tank is cycled, the nitrate levels can get high. Cardinals require rather clean water so weekly water changes are best (and nitrates under 5 ppm is a good practice for these guys from my understanding). Also, pH is an issue - Cardinals are often wild caught and these fish need acidic water - high pH can harm them. One or both of these issues could kill them overnight.

    The other fish you have are tough and can stand high nitrates so you'd only lose Cardinals and not know this unless you tested for it.
