Hmm... If you do decide to get cuttlefish, 1.5 month babies are a great way to get started. For a first-time ceph-keeper, they are easier than eggs. They are already eating bigger food (rather than mysids or amphipods ) and they are large enough for you to be able to see them eat. They will be getting too large for a breeder soon. Good luck. I was considering upgrading to a 92 gallon corner tank, but I may reconsider since you are having trouble fitting things under your tank...
