Not sure with cardinals in particular, but for lemon tetras I've had two
batches both times triggered by extended periods without water changes (1-2
months). I don't top off the water or change ANY water during that period,
I just let about 1/2 of a 20 gallon tank evaporate off. I wasn't using
fertilizer at the time either but the plants didn't seem to care, I would
assume maybe from increased concentrations in the tank as the water was
evaporating off.
After the long "dry season" period, I would do a BIG water change, about
1/2 to 2/3 of the remaining water in the tank, leaving only maybe 3-5
gallons in the 20 gallon tank. I then fill the tank to it's usual level
about 1.5" below the top with fresh water. The tetras would spawn at some
point after the big water change, not sure when but I'd see small tetras
within a month or two after the big water change.
