One of my cardinal tetras are dying. The tetra is not moving and they were stuck in the plastic plants 3 times so I had to free them each time. The tetra seems healthy and I did a water change to prevent the tetra from being on the ground, but it didn't work. They're breathing rapidly, lost some iridescence near the top fin and cannot swim with the others. Does this tetra have disease or are they healthy-looking but dying peacefully?
