Blackwater guru
Fish Fanatic
I am gonna get myself my first aquarium which will be a 160 liter blackwater setup designed to mimic the habitat of cardinal tetras with lot's of floating amazon frogbit plants at the top along with leaves and driftwood made out of oak on the bottom.
I will use low flowrate filtration intended for larger tanks with 10 cardinal tetras which is small but still big enough for them to show natural behaviour and colours and to keep maintenance low along with healthy fish.
The question is how many of them should I add at once after the tank has cycled?because the ones at my local fish store are wild caught which means they are more sensitive to drastic changes in water conditions.
I don't want to kill my new fish by mistake which is why I am asking this question.
