Octopi can change color in a split second. They usually like to match their surrounding and are able to match the color of the background to camouflage and shape their soft body to the texture of the object or background they are imitating.

You can feed your pet octopus any meaty food like frozen shrimp, krill.

Best is to supplement with live food such as our grass shrimp saltwater feeder shrimp.

Any size aquarium tank will do for these little octopus.

Keep in mind that this little Octo is a juvenile of an apex predator.

So while it is small so it can't eat larger fish and crabs, it could eat smaller animals in the aquarium.

A unique way of housing this little predator without the risk of it hunting down your existing fish and shrimp or bothering your seahorses is setting up a show refugium to the side of the main display tank, can be 15 gallon size. 

The refugium will act as a biological filter for your main display tank with Saltwater plants and the Octopus will be in heaven.

Or a Bio Cube or Anno tank, small stand alone tank that you can add corals, macro algae, snails and other animals that are compatible with the Octopus King.

How do I feed my Octopus? How often do I feed my pet Octopus? Why can't I find my Octopus in it's tank?


The best way to feed octopus is by just having some live food in the tank at all times. Alternatively, you can hand feed Octopus with frozen shrimp or silversides, but it's up to the keeper of the tank how much time you want to spend on hand feeding it. 


Octopus do not have to eat constantly like many fish. They can go weeks without eating.


It's an expert at hiding in plain sight and very intelligent. If it knows that you can find it in it's present home or that you can see it then it will adapt and try other ways to fool you by camouflaging itself or change hiding tactics and location to see if that works. 


 It can start to take a liking to you if you’re the type that leaves your hand scent in the tank often to work in the tank for example, when you clean your tank or when you feed them. It can then eventually, like a dog or cat, start interacting with you like it's trying to develop a relationship with you. But it's up to the individual Octo personality what it decides to do. Part of having a level of intelligence means that the organism has an individual personality. 


When first introduced to the aquarium, the little Octo is sitting in it's place of safety trying to figure out how safe it is. It's determining by your demeanor when you approach the aquarium if you can see it or not. It's safety depends on stealth and it's ability to hide in plain sight. It’s hidey hole must have openings from which it can also escape predation. For now it probably sees you as a potential enemy or predator. The last human that it dealt with and smelled, took it away from it's home and mailed it in a small box to you.


Octopus’ have excellent memories so it's not going to forget the first encounter it had with a human that took it from it's home on the reef. Just a question of trying to let it know that you’re a different person/ human that wants to love it, give it abundant food and good water/rocks to live in.


Another thing, Octopus are experts at taking objects like shells and sticking them to their body.  So all you see is a shell stuck onto a rock or in the substrate. They can contort themselves to any shape and color combination.


The few scientist that have done studies have said that Octopus have a life span of 2 years, but this is just mostly conjecture and guesses. Not enough is known yet about the octopus life.

Case studies have shown that Octopus are as smart as domesticated cats. The pet Octopus will eventually figure out that your a safe person to be around.


I’m seriously considering purchasing a new pet octopus.


Are your rusalty octopus king tank raised or wild caught?


Our babies are wild caught. They are the healthiest octopuses available anywhere.


We hand collect our baby octopuses with no chemicals or traps of any kind. We are the collector and seller of our octopus, they are fresh caught days before you receive them to minimize stress from multiple middlemen handlers and the further stress of weeks spent changing hands before you receive them. After we catch them we continue to keep them in a healthy stable environment and make sure they are disease free while they await their new home in our customers tanks. We have all the live food and stable habitat tanks to keep our octopuses healthy and happy.

If I do choose to feed frozen food to the octopus, do you just drop it in the tank or do you need to hand feed that?

It's good to supplement non live food along with live food like frozen, shrimp, silversides, and or clams also. Try dropping the meat in first and observe what happens. Don't let the meat rot before you pull it back out again if the octopus doesn't take it right away the first time. Most likely it will eventually take the meat. But the first time it will be cautious and wait to see if it's a trap your setting for it. Once it learns that it's safe to take non live food you drop in then it should be good from there on.


Having a pet Octopus is definitely the most fascinating aquarium experience I’ve encountered. Absolutely amazing animals. 


That's wonderful to hear. Thank for sharing your thoughts.

Remember to think of the octopus as a pet with intelligence like a dog or a cat. So the more you treat it in an interactive way the more it will domesticate and start interacting with you.
Add your sent to the water by dipping your hand in the tank every once in a while during feeding time so it starts equating your sent and the sight of you with good feelings of trust and well-being.
Just like you do when you befriend a cat or a dog. Soon enough it will start trying to communicate with you by flashing colors and different shapes at you. This is the octopuses language.
My Octopus laid eggs. What can I do?
In case your Octopus happens to lay eggs. Here's what you can do if your so inclined.
That's so wonderful. Keep the Octopus egg nest tube somewhere where there is some water movement but not too much and let the mother take care of them. They should hatch within 10-20 days.
They will be the size of the egg when first hatched because they are balled up inside the eggs. Then they stretch out a little so they will look slightly larger than the egg.
More than likely the mother will take care of and protect the eggs until they hatch and then she will die shortly after she makes sure her babies hatched and survived.
The babies need to be fed live foods to have a chance of life. Different sized live feed while they grow larger. Starting with baby brine shrimp, then Mysid shrimp and Amphipods.
The problem is that they have to be hand fed similar to our own human babies for them to have a chance to grow large enough to have the ability and energy to hunt their own food.
One way to accomplish this is to confine the babies in a small manageable space or culture tank that keeps the live food concentrated and swimming or crawling close to the juvenile Octopus at all times so the baby octopus doesn't have to spend all it's energy to find and catch the prey often enough throughout the day so they don't starve in the interval between feedings.
Like our babies they need to eat small amounts but often throughout the day.
The culture vessel can be a small container with mesh placed in the main tank that allows water to flow through with a small gentle air stone inside to circulate and push water exchange out of the mesh.
One option for a container to use and set up in tank, is something like a guppy fish juvenile grow out mesh net box from local pet store.
Another option is a stand alone culture vessel which will present it's own difficulties since it has to be maintained with good water quality at all times.

Octopus review
Written by David Hernandez on 17th Apr 2022

Surprised and excited what I recieved. Was nervous about the first week. I'm about to be on week 3 with a healthy and happy octopus she loves to eat red claw crabs and hermit crabs (live) I watch her explore the tank and handel and play with her under a red light. (Only got bit once lol , was like a bee sting) fascinating creature. She seemed to be fully grown, hopefully I'll have her for a while. Ready to try on a bigger octopus in the soon future.

Is this octopus venomous because I want one for my birthday but is it also freindly and decently trained like moving around and how big of a tank should I get and should there be fish? And what kind of fish and are all cuttlefish poisonous and are squids allowed with an octopus because if squids and cuttlefish and octopuses live. Answer: This octopus is not poisonous. Most octopus and cuttlefish and squid are not poisonous. Our octopus don't grow more than 4 inches in size so they are more fish safe than larger octopus. You will have to find out by trial and error which animals you can keep with them in the same tank. Some poeple are able to keep dogs and cats together as pets and other people can't. also other factors like each individual animals temperament/ personality will determine the outcome. There's no exact all encompassing answer to the question of what animals will get along with each other. Also food availability and environment in your aquarium will make a difference. ie. if each animal had it's own space to feel safe in which will encourage them not to bother each other.
