Why did my cory catfish die?
Yes, some people thought my tank was a little overstocked - but I’ve been looking after it so well!
- I have a 28 litre tank, filtered and heated to 26 degrees centigrade.
- I’ve had the tank for 1.5 months, and the fish for 1 month.
- I have about 8 plants in the tank (they have root fertiliser in the gravel and receive a drop of leaf fertiliser 2/3 days). I leave the light on for about 9 or 10 hours a day.
- I do weekly 30% water changes and add conditioner/purifier every time.
- My ammonia, nitrite and nitrate levels are all 0. My pH is 7.
- I have a Siamese fighting fish, 5 cardinal tetras, 5 rummynose tetras, 2 (originally 3) albino corydoras catfish and 2 otocincluses.
- I feed them 6/7 days. They seem so happy and healthy.
Except I found one catfish dead last night. It looked perfectly healthy, but was definitely dead.
What could have caused its death? Was it just a particularly weak little fish or…?
I can’t understand how any tank conditions could have contributed… although some people say my tank is heavily stocked, the reputable fishkeeper/seller who sold me them told me that he has had many successful tanks of the same size and stock.
Thanks in advance.
Thank you for your answers so far. What I don’t understand though, is what is “poor water quality” when my tests all indicate that water parameters are fine? And I know that my kit works because a few weeks ago it showed a little spike in my ammonia and nitrates, but that has now equilibrated. The kit was expensive, too, so I hope it works!!
