Hello everone im a newbie, I was reading quite a bit about how to set up and equipment i am suprised that even when i am set up that i will have to leave the tank with nothing in it for 3-4 months. I suppose it will probably take that time to find an octupus for sale! :shock:

The company i will be buying equipment off here in ireland is and im just wondering if you guys could supply me with a shopping list of what exactly i will need or even if am better off ordering from you guys im not sure. :oops:

I am also wondering is my tank too small it looks huge to me here are dimensions.. i think its 40 gallon breeder judging by my research..
:arrow: L=40" X w=18"X h=16"
Maybe im better off just getting fish :cry: but this is a little dream i have :rainbow:

1. You'll need a filter, wet/dry. canister, power, and there are a lot more. I think a lot of us use wet/dry since it adds extra oxygen to the tank which is crucial for an octo to survive.

2. Protein Skimmer, another important part to octo tanks. One of these will get all the gunk your filter misses.

3.You may need a heater depending on what the average tank temperature is and the species you get.

4. Substrate, you can use very fine sand, about an inch for our o. bimaculoides but you probably can't get one in Ireland.

5. Live Rock, about 2 pounds for every gallon of water.

6. An RO filter can remove a lot of impurities but are costly, a lot of us use RO water since it is a lot cleaner than tap water.

7. You'll need test kits so you can know when your tank is octo safe.

8. Lighting, octopus don't need special lighting and many would rather have none to a very small amount.

9. Aquariums, depends on your species, a bimac would be a little crampred in a 40 gallon.

Hope this helps! :)

Hi and welcome to! :welcome:

Nick has given you a good start. We have some articles on our Ceph Care page (click on Ceph Care above) that might help you work through the details. Look at Colin's Equipment List, also the Checklist to start with.

I found that one pound of live rock per gallon is quite enough - otherwise you'll cover your entire "beach" area.

Colin can probably give you some more advice since he lives in the UK (Scotland) and knows better what's available.
