Thanks for answering bro taufiq. I will most likely purchase that then, cycle and mature for 4-5 months(might not need that long but I just want to be sure), add some beginner corals that can be kept with cuttlefish, and if the corals survive for, say, 5 months, then I will buy the cuttlefish. A bit long, but I want to be sure the cuttle can survive. If corals can, then cuttles should too.
