I cannot believe how used to humans my platys have gotten after only 2 weeks in my aquarium. When I feed them they come right to the front/top of the water, and if I put the tip of my finger in the will come up, and swim around it, and sometimes nip it. I have never had fish such as Tetras do this before, it is pretty cool. Also they are right behind me, and when they are hungry they come to the side of the tank I am near. Has anyone else had there Platys do this?
