I'm a experienced reef keeper looking to branch out. I've decided my next tank is going to be for and octopus. I belong to the Monster fish forum and they lead me here. My question is am I heading in the right direction. I was thinking of getting a cub tank 24"*24"*24" which is about 60 gallons I'm also going to use a refugium and a protein skimmer. Will that size aquarium be sufficient, and what species should I start out with. I seen a blue ring in my local salt water store and was hooked, yes i know they're poisonous but all the cool animals usually are (dart frogs). Thanks for any info.
