Hello all, i am new to aquariums and octos, my friend is selling me his tank and i thought what a great pet an octo will be, so i started researching it and Ive been stuck on tonmo for a while now thanks to its abundance of knowledge. anyway I'm Ross I'm from central Pa. ( Penn state) I'm 26 and i have always been fascinated with the octopus' cammo abilities. My tank is 30 gal. and i know i cant have a larger ceph so im wondering if there is an octo that is not a dwarf but will live comfortably in a 30 gal? if not i will use it as a sump and buy a larger tank. or i can put other saltwater creatures in it. the tank is a bio cube so it has a built in filter and unsure of whatever else in there, and the plan is to buy a LR, some LS and a few crabs for the cycling process and try to build up the bacteria as strong and healthy as i can before i buy my new buddy. so thank you all for your amazing forum and kindness to newcomers, any and all info, help, input or just hellos are more than welcome.
