What are you trying to get? You've made several posts recently about 3-4 different types of octo's and now cuttlefish all with different sized tanks.... You need to slow down, here's a list of questions that you need to answer for your self right now or soon, before you do anything else, otherwise you're going to get no where, and make a lot of mistakes.
What tank are you going to get (so far you've mentioned a 65, 34, and 300 gallon, which one are you going to get?)
And What type of Ceph do you want? (cuttlefish or octo)
-to answer this you need to answer these questions:
1) How much do you want to spend on food? If your answer is less than $30-$50 a week, you're going to want to go with something that will DEFINETLY eat frozen food, right now captive bred cuttles from thales and paradox are the only ones on the market that will do this.
and 2) What size tank are you going to have (if it is less than 55 gallons but more than 30 or so, you're going to want to go with cuttles unless you want a merc)
Have I missed anything here?
Basically, you need to go slowly with this. I've been "planning" on getting cuttlefish since I joined tonmo, which was a year ago this month, and still am at least 3 months out. I've been working on setting a tank up, doing my homework, and getting it right during that time.
