Quarantine question.
A few weeks ago I bought a little koi and put him into an inside tank for the winter. He is with 2 other fish but they are not from the pond.
My question is: Come spring when I am going to put him out in the main pond how do I do this. Should I bring another fish inside from the pond a few weeks before I know I'm going to put the newbie out? How soon should I expect to put him outside?
I'm sure there will be a temp difference in the water. Do I bag him and float before adding?
