Garuf said:How are you finding them in a dosed and co2 injected aquarium? Are they as touchy as people suggest? I see you're using ADA aquasoil do they mind the lower ph?
Garuf, i find this page about Cardinals:
This also says there are no problem with Aqua Soil.
"The tank consists of ADA Amazonia substrate, a temperature of 84F and a pH of 7.0. Some have stated that the low ph of 7.0 due to the ADA Amazonia is not good for this species. Right now I disagree. All of the Sulawesi Shrimp that I currently house are doing very well in this setup and so far even the babies are doing very well. The babies are constantly picking away for food which is of course a good sign."
