Ruby sharks are very teritorial fish, they need a hiding spot or they might die of stress. Here are some things you could get for them, of course a fake or real plant, a rock, maybe a hollow hidding place like some drift wood or a tube. They may stay at the bottom for a long period of time motionless.
They often are nocturnal in my experience, well thats maybe because all of my fish are nocturnal. Ruby sharks dont like a lot of sunlight so only turn on the light during water changes.
Telling male from female. Often the males are much smaller, the females almost always look pregnant, they have big bellies and may turn towards a silver colour, boys, on the other hand are slim and have a black outlined anal fin.
