I have plenty of experience keeping reefs and octopusses. I am thinking of setting up a cuttlfish tank. Since it is going to be new I would like to get recommendations. I am pretty much open to getting whatever. I was assuming a 55 or 75 gallon aquarium with a sump a. Is that too big? I am planning to add a chiller because it gets freaking hot in Houston. What do the experts say?
