Hello, today we bought 2 betta fishes for my kids, one each, this will be their first pet, so I am very nervous of doing anything wrong, but I think I just did :(, I really did not do any research on the Betta fish before, but as soon as I got home I searched for info, I found this site and explains how to take care of them very well. It said that I was to clean the tank and accessories, remove the clorine of the water and put them for 15 min on a plastic bag to adapt to the temperature, now I did everything but to take the clorine off the water since I did not know and didn't buy anything to do it, now I have them in a bag flooting on top of their new tank and I am scare to put them in, how long should I wait before I let them swim in their tanks?
