I was thinking a taller tank is better for them but I just picked up Cephalopods: Octopuses and Cuttlefish for the Home Aquarium and it suggests a longer wider tank. I will keep as many as the tank is suited for. I have 25 babies right now but won't overstock the tank. I want to get my tank next week. Already have lots of live rock curing, return pump and all that. Just need a skimmer, tank and lights. I was thinking 36x24x30 which is 112 gallons, but seeing as this is a custom tank its a little expensive. Would a standard 90 be better? I don't really want to go any bigger and prefer a 3 foot tank to a 4 foot tank due to space constraints but obviously I want what will be best for the cuttles.
