I don't understand what I am doing wrong. My cardinal tetras are dieing. Initially, I purchased eight last week and now I have only one.
The first died on the trip home. Another died because it got caught in the filter. The third died within 24 hours. The forth jumped out of the tank. The other three died within the first week, leaving only one.
I have a 20 gallon tank that is heavily planted. I do fertilize with macros and micro nutrients. I also inject CO2 with the yeast method using a 2 liter bottle. My water parameters seem normal. Ammonia-0, Nitrite-0, Nitrate-10. My Ph is around 7.0. My water is a little on the hard side with a higher Ph, but the CO2 helps to bring down the Ph to neutral.
I'm not getting it; I'm not sure what the problem is. I've had aquariums for years and I've never lost fish like this. I've had a 90 gallon tank with discus and never had a problem with that. I think discus are easy compared cardinal tetras.
