There are almost as many different quarantine processes as there are aquarists in the hobby for more than 10 years. About the only thing there are more of are uninformed hobbyists who claim a quarantine is bad for fish, or who don't want to spend the time, or inaccurately claim not all fish can or should be quarantined, or who don't want to spend the $40. for a quarantine kit, or who don't believe it is necessary, or who believe that a healthy fish can survive any disease or parasite.
We, the Old Guard, for the most part know better. I wrote . . .more than 10 years because if you've been in the hobby that long, you've come to realize that performing a quarantine process is essential to good marine husbandry. The smarter aquarists know this from the outset and began using a quarantine process from the first day in the hobby! :thumbs:
What good is a quarantine process? There's a whole list that a quarantine process will:
1) Further acclimate the fish to captive life without being bothered by other fishes;
2) Get the fish to eat without it 'running away' and hiding;
3) Get the fish on the right foods and nutrients;
4) Allow the fish to eat without competition;
5) Give the fish a chance to recognize and become acclimated to the aquarist;
6) Give the fish a chance to heal any capture or travel injury or trauma;
7) Give the fish a chance to recover from any condition or disease;

Prepare the fish for a more competitive life in the community/reef tank; and
9) Protect the health of the display tank livestock.
