make sure the pudding isn't too soggy but that just ruins everything
Okay, I'm starting to get a little bit worried about my fish. At first everything seemed fine, but for the last hour or so they have been standing still right at the surface, and doesn't move from there. Is this just stress from being in a new, previously uninhabited tank or might there be something wrong?
Do not worry much unless the fishes begin to list to one side and cannot maintain their attitude in the water. Other indications of potentially serious problems are cloudy eyes or dulling of color... but this can sometimes just be stress of a new environment.
Also, sometimes adding too many animals at once can cause heavy stress and water quality fluctuations...
Most issues begin with stress, and if the fishes can overcome it, they can overcome the sickness/distress. If you cannot resolve the issues causing stress, even hardy fishes can have trouble and are more susceptible to diseases and such.
Give it some time, hope for the best. Try to maintain good water and watch for signs of sickness.
