If you have a community tank that you absolutely cannot endanger, then a Quarantine tank is a must whenever you add a new fish . I , too have not followed
this advised of late ( dismantled my q tank ) and recently had my 2 tanks develop a ICH outbreak because of 3 new dats that i didnt Q.
I was lucky it was only ich. But still, it was a hassle and my tigrinus had it real bad. Had i not acted fast i couldve risked losing the tig. All of that because i didnt Q.

Now i always quarantine my fish, or i just ask my lfs where i work at to hold the fish i want for a couple of weeks, so that I know it is disease free by the time i bring it home
