Mixing corals rays and coral cat sharks

[M3AN ONE]

Has any one had success with mixing corals lps and sps with rays and coral cat sharks?
I have only heard of one case where the sharks became to active at night and started to knock down the sps corals.
I am curious if this is a common occurrence.

Miniature wrecking balls! Best to do a specific shark tank.
