let me start off by saying what a wonderful site! im a soon to be octo owner! ive owned a salt water tank before. always wanted an octo, but i knew it would have eaten all my fish:) anyways. does this tank sound suitable for a octo.. its the nano-cube 24g. says it comes with everything.. but theres always a catch. and another question i have is, am i gonna need a chiller? i understand these creatures love cold water and its vital for them to live in cold water for them to survive. just how cold of water though? where do you get food for them, only solution i see is buying crabs from the local pet shop. i really think im ready for one! im just skeptial on that particular tank and the supplies i'm going to need. can anyone help me out?
