Hi,
One of my female swordtails is lying upright (propped between filter and glass) in my tank. its hardly moved over the last two hours and its scales look slightly shiny green. Also the fish has a small chunk missing from its tail and when it does move about it drags its tail along the gravel. A few days ago I noticed that the fish was swimming very wobbly, waving its body about more than normally.
Just a few weeks ago (whilst I was away) my parents informed me that a balloon mollie was swimming oldly and it died a few days later. I have just conducted some water tests using an
API liquid water
test kit and the results are as follows:
pH - 7.2
nitrite - 0ppm
ammonia - 0-0.25ppm
Nitrite - 20-40ppm
Any help would be much appreciated
