So I just did a 50% PWC on my 10 gallon planted. About 5 minutes after the water change, I noticed one my cory habrosus not moving on the bottom, on his side, and eventually was dead .
I had 6 of these wonderful fishes in the tank, now down to 5, all of which were active before and no issues whatsoever.
I have 2 suspected reasons why it died, but I want to ask you guys what you think might have happened.
- My 1st hunch is the cory died of oxygen overdose , if there is such a thing. I was filling up the tank straight from the tap using my gravel hose, it's a small gravel vac which the tube fits the faucet. The tank is placed on top of the kitchen counter so the faucet is accessible. The flow of the water causes enormous amount of microbubbles that filled the tank. I noticed my cories were darting to the surface to breath during the time I was filling the tank. They did not do it the 3 previous times I did PWC the same way.
- My 2nd hunch is, I made a mistake of putting prime after almost filling the tank with water . The cory might have died of chlorine poisoning.
The tank is fully cycled. I always make sure that when filling the tank that the temperature of the water is almost the same through feeling (which I always do even with my 60 gallon). The remaining cories are somewhat inactive right now, and I am afraid for the worse. So what do you guys think happened? What might I have done wrong?
