Yea I saw this, and I don't think all live fed behave like this, she's never bitten before or even attempted, I opened her tank tonight to move her water dish and she instantly went into feeding mode so I figure she's hungry.
Feeding mode - She begins to move around quite fast as if searching for her prey, she always does this before she strikes her food so I instantly recognised it and I got the hell out of dodge and closed her tank, so I guess I'll move up her feeding schedule to Monday.
