Hi Tonmo, Just wanted to say hello and introduce myself. I am in the process of building a 50g breeder for a future Octo. I have been keeping fresh and marine fish and inverts on and off for about 20 years. My current 29g was going to be for a single fumanchu lionfish but then I saw an octo at my LFS. He is by far the cooloest thing I have ever seen in this hobby . Once he changed color I had to have one. Since then I have been researching and feel I am ready to make my first attempt at keeping an Octopus. The LFS has him as a pacific red octopus . They are asking $100 and he is very small. Usually when I go in to look at him his eyes seems shut. The guy who works there says he hasnt eaten any damsels they put in but will jump all over any crab. He also said he seems more active when he first opens the shop and lights have been off. I would say he is no bigger then my hand. This guy will probobly be gone by the time im ready for him. My plan is to take everything I currently have in my 29g which is still cycling and move it to the 50. I will then use my 29g for a sump. I have 50 lbs base dry rock and 7 lbs live seeding it. Anyhow I just wanted to say hello and I will post more as I get closer to setting up the 50.
