i think I clicked the right thing. But anyway, i've been wanting an octopus for years and my mother finally broke down but before i can get it i have to have solid proof that i did the research, so i figuered you guys could help me. also from all the people that i've asked i keep getting different tank sizes. what is big enough for an octopus but still not unreasonably expensive? oh and how pick are they about the water qualtiy?
