DO NOT USE DISH SOAP!
This is a terrible idea. Fishless cycle your aquarium with plain ammonia(cheap), use Stability to speed it up(if you are impatient), and once you have it cycled (0-ammonia, 0-nitrIte, nitrAte>0) then add your fish. No use spending money you don't have to on fish you don't want.jdcampos;4872351; said:If you are planning to put expensive fish in it, I will suggest you put some test fish first after cleaning the tank very well. Atleast this way, if you lose the test fish, you will not be too worried.
