Just wanted to bring up this topic and see how everyone's fish sleep... because the other day I went to turn the lights on, and they had been sleeping because the room had been relatively dark that day... and for about 10 minutes I thought they were dying and was ready to do a massive water change! The fry were like, stuck against the walls of their net breeder, the platies in the tank were just in the plants, hanging there stiffly... I thought I was going to lose them! But then they woke up and jumped back to life! Is that a normal sleep pattern?
