I have been trying to get an octopus for over 1 year. Finally (after I gave up home and took down my 30 gallon cube) I found one. All I have is a 6 gallon jbj nano cycled for holding. Which is fine as the octo is very small and quite frankly I was not expecting it to aclimatize very well. Thankfully it did and it is awesome! Eating shrimp from a stick as is very interactive after 3 days It was sold as a Bimac, however I am thinking it is a Vulgaris so want to make sure I have a big enough home for him. I went out yesterday and bought a 72 gallon with an air tight lid with a rena xp4 canister took out the media and filled with live rock. I siliconed the hoses into the lid so there are no gaps. No skimmer right now however that is my first question is: 1. what skimmer would be the best for this setup and what precautions could I take to make sure the octo is not sucked in to the intake. I was thinking I should wait to buy one until he gets a bit bigger. 2. A friend is selling me 35 lbs of figi rock and I have about 10 lbs in the tank he is in Both have been established for over 2 years. If I move it to the 72 will I see much of an ammonia spike? 3. Will a 72 be o.k. for a solo vulgaris 4. How should I decorate it? 5. Would I be o.k. bare bottom, or should I have a sand bed. 6. Tips and suggestions on moving the octo to his new home would be appreciated I realize this is not the best situation, however please understand my hopes of getting an octo were gone. I just could not pass this up. Any help would be appreciated.
