Hi all. I just bought some Anacharis at Petsmart and ran it under some warm water for a few minutes then left it in a bucket of cold water for a few hours. That was the extent of my "qt" time. I had bought it there before and introduced it with no problems. I am wondering if I should pull it from my 65 gallon aquarium and QT it properly, or if its too late since I introduced it about an hour ago? I have 1 koi about 3 in. And 1 goldfish in there. The koi ate all the other plants except the Anacharis that has been in there from the beginning. They are just now starting to pick the "leaves" off of it. I figured put another one in there and give the other a rest while adding to the aesthetic of the aquarium. Any advice would be appreciated!!
