ok I feel silly asking this but here we go...so I started this new hobby about a month ago and my local guy has never mentioned "acclimation" but I read a lot about it over the internet. The couple that runs the store where I'm at, have had it since 1964...so I feel like they should know what they are talking about..or do they...so anyways...I guess the question is: Do I have to go through the process of acclimation every time I introduce a new fish???
