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.

my sharks are pretty active, the albino in mine is quite teritorial he chases the other male and female around and also all my other fish but my plecs, angels and my silver shark. but they do add a good sense of natural order.

I just got my male red-finned shark today. He seems quite active right now--need to get him some driftwood and/or caves. I got him along with a cory cat. They were tank mates at the pet store, so I assume they will be good together. Right now, they seem to take no notice of one another. Wish me success...here we go!

I have both a Rainbow Shark and Albino Rainbow Shark in my community tank.
They are very active YET peaceful and interesting to watch - During the day - With the lights ON.
Forever looking for food, they even come to the surface at feeding time - the albino even takes flakes from my hand.
I have NEVER seen them nip or fight.
And they get on very well with my 2 Pakistani Loaches
