I have had my 40 gallon tank for a year now and have not had a fish die for about 6 months, so my environment is pretty stable. I have 12 community fish in my tank right now, and I want to add new fish, but I don't know if this would be stressful for them since they have been used to this environment for a while. Also, if I do add new fish, would it help to clean and rearrange the decor before adding the new fish or would that make the transition even more stressful?
