Is this normal?

I just added 3 burmes zebra rasboras to my tank. I was originally concerned about adding such a small fish with my larger fish but what they have done shocked me. I have what looks like an old run down house for my rainbow shark to hide in and plenty of plants that I thought my new little guys would love to hide in. Well they have decided to move in with the shark. Is this normal? Next to the zebras the shark is a giant we even renamed him Sharkzilla. I think it's neat the big guy sharing his home with the little guys, I'm just curious if this happens often.

I don't have those fish but my kuhli loaches share the same caves as my bushynose and he is generally a bully in the tank. but every fish is different. you could very well have a unique situation.
