I have a mickey mouse platy and I have a question about her behavior. I have 2 ornaments in the tank as well as a thermometer and heater. At times I see my platy kind of biting at these things, it looks as though she is kissing them. She goes up to them and lunges at them and bounces off. Can anyone explain this behavior? Is it normal? I wasn't worried at first but just wanted to make sure she doesn't have a mouth parasite or irritant she is trying to relieve. Any help is much appreciated!
