Comments: These are SAID TO BE nocturnal. Mine are VERY active during the day. They're said to be territorial: Mine are very happy to share space. They are said to be shy and in need of caves: Mine NEVER use the caves. They NEVER hide. And they NEVER sit still. Trying to photograph them was Difficult.
In my personal experience:
Happy little DAY fish. Always doing something. Not shy. Happy to share the community tank.
