They are large (6"), social, and highly active, so they need a large enough tank that you can keep several. At least 4' long, and larger is better.
They thrive in cooler sub tropical water, room temperature to mid 70s. Not a good tank mate for Discus or Angles. Good with the cool water Rainbows.
They are big enough to eat smaller fish, so I would keep them with fish that grow to at least 2" long, or longer.
Accept a range of water conditions, come from water that can be soft or hard.
Being a shark shaped fish, I would not keep Red Tailed Sharks, Flying Foxes or other aggressive relatives with them.
I have not heard that they eat plants, but they are big enough and active enough that I would suggest sturdy plants that are OK if the fish bump into them. Some of their relatives are noted algae eaters (SAE) but I do not know if these guys are so great that way.

They prefer large groups also - If you can't have a group of 7 at least it is probably better to get just one.

Could you keep a small school of them in a 56 gallon?

You would probably be okay depending on how the tank is scaped. Like I said it is best for them to be in groups of several fish. I would recomend at least 7 fish. They can get somewhat large.
Is your tank a 55 long?

What is the foot print and height?

It's best if they have length to swim as opposed to height (depth).

I have a feeling that these would not be the best fish for your tank.

They grow to be 6"

i have five four inches in a 90g. They are great fish. Don't think they would do well in a tank with a smaller foot print to be honest.

They do however like to nibble at moss. Especially Fissidens. I have four branches of Fissidens in my 95G and I always see them pruning on of the branches but leave the other 3 alone.

A little bit off topic, but I see rose lined sharks selling for $4 at my LFS, when I visited my friend I saw he had a tank with 20 or so specimens, all around 4 inches with a distinct difference; there's a black and yellow/white pattern on their tail fins, he tells me these are different and cost $15 each, can anyone confirm as Google has failed me.

Is it a different species of RLS? Or is he just yanking my chain?

All roselines should look like this

I've seen a variation of long finned roselines with white dots instead of yellows. The owner said they originally were like the ones in the URL above and changed into the long finned variation but I don't really believe it...
