So I was browsing through the forums and I clicked a link that led to a beautiful tank video, and somehow came across this video, which I thought was absolutely endearing.
As you can see, this person clearly loves their fish, and this fish loves them, and the owner knows how to be careful with his fins as well. And I thought that would be incredible to be able to stick your hand in the tank and play with your betta.
However, my question. Sanitation. Even after washing your hands, isn't soap residue bad for fish? I can't think of any way that would be safe, even anti-bacterial stuff. Do you see how this could be safe for the fish in any way?
