I have a black molly. He was acting normally until after Sunday when I did my first water change. Now, he hangs out in the bubble house (ornament) all the time. Even during feeding time, he is hiding. Last night, I saw him hanging out at the top of the tank next to the water heater looking like he was kissing it. He stayed there for a long time. Now, this morning he was back in the house again during feeding time.
Is he sick?
