Just curious... do bettas usually sleep all night? I got up to pee at 4:00 AM and Lila was swimming around in her tank. Whenever I saw Shiny at that time, he was always sleeping. I don't know about Fishie because he's in the other room and I've never checked on him at night.
They were all sleeping when I got home last night, though. It was only like 9:30! hehe but there were no lights on. I tried to feed them but they were all totally uninterested because they were still waking up. They all ate enthusiastically about an hour later, though.
