Deep water corals for an octopus tank

[Thereefdoc]

Does anyone have any experience with deep water/colder water corals? I have an octopus and I want to keep some corals in the tank with him. As of now I have some gsp and sun polyps and they’re doing pretty well. The tank temp ranges from a low of 68 to a high of 73. On average it sits at about 70. Any recommendations would be greatly appreciated!

They would have to be non stinging like soft corals.
