How to take care of baby octopus?
You can look for them in tide pools during low tide during the evening, which is by far the easiest option. Once the octopus eggs hatch, you will need to feed the offspring properly. Baby octopuses should be given mysid shrimp, small crabs, and the larvae of various crustaceans. These foods will help juvenile octopuses to grow strong and healthy.
What are octopuses favorite food?
Crabs, shrimps, and lobsters rank among their favorite foods, though some can attack larger prey, like sharks. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animal into their mouth.

How do you care for an octopus?
Octopus is a less maintenance animal; it doesn't require much care. The best circumstances for your octopus pet can result from maintaining their water tank regularly. Most of them tend to become inactive if their natural habitat fades away. Hence it's important to keep their natural habitat intact and well-nourished.
How do you keep an octopus alive?
The best way to keep an octopus is actually the method we originally recommended: a tank of adequate size or better, lots of live rock in the tank (a pound per gallon), a one-inch sand bed, a wet-dry filter and sump, protein skimmer, powerhead for extra circulation, and a simple fluorescent light.
How long can octopus stay out water?
around 20-30 minutesLike fish, octopuses need water to survive, and take in oxygen through their gills. But marine biologist Ken Halanych told Vanity Fair that octopuses can survive for around 20-30 minutes outside the water.
Can I have a pet octopus?
Octopuses, in general, are not a great choice for a pet. For one, they are incredibly intelligent and seem to easily get bored. One study [pdf] revealed that octopuses in small tanks outfitted with flowerpots, stones, beads and shells still showed signs of distress and even self-mutilation.
What is the lifespan of an octopus?
Giant Pacific octopus: 3 – 5 yearsOctopus / LifespanThe giant Pacific octopus, also known as the North Pacific giant octopus, is a large marine cephalopod belonging to the genus Enteroctopus. Its spatial distribution includes the coastal North Pacific, along California, Oregon, Washington, British Columbia, Alaska, Russia, Japan, and Korean Peninsula. Wikipedia
Why does an octopus have 9 brains?
According to the Biogeo Planet, the octopus is considered the most intelligent creature because it has 9 brains. But how does an octopus utilises 9 brains? Actually, each of its eight brains helps in controlling the arm movements. And, the centre one for other activities.

Most of the time they're yellow or sand-colored, but bright blue rings appear on their body when they're about to strike. They'll strike only if they feel threatened. If a blue-ringed octopus does bite you, you need to get medical treatment immediately because their bites can be fatal in a short amount of time.
Can I keep an octopus in an aquarium?
An octopus is one of the most rewarding marine creatures you can keep in a home aquarium. We are fascinated by their behavior, ability to learn, and their stunning shape and color-changing abilities.
What Is An Octopus?
The common octopus, scientifically named Octopus vulgaris, is only one of nearly 300 species of octopuses worldwide. Octopuses are ocean creatures that live in coral reefs, small crevices, and under rocks on the ocean floor. They possess several unique features, including eight arms and bulbous heads.
Diet Of The Octopuses
There are two types of octopuses with regards to their feeding habits: bottom-dwelling octopuses and open-ocean octopuses. Bottom-dwelling octopuses primarily feed on mollusks, polychaete worms, and crustaceans such as clams, shrimps, lobsters and snails. Open-ocean octopuses feed on fish, birds, and snails.
Feeding Adaptations
During feeding, the octopus uses a strong and powerful beak to bite its prey and inject it with venom. This venom does not kill the prey, but rather immobilizes it so that the octopus can easily feed on it. Once the prey becomes immobilized, the octopus uses its beak to grasp and rip the prey apart into smaller pieces.
Pet Octopus Appearance
The octopus is part of the mollusk family, which includes snails, clams and squids. Most squids won’t grow any larger than 14 inches when they are kept in a tank, but they can get much larger in the wild.
Behavior
Researchers have observed signs of extreme intelligence in octopuses, both in captivity and in their natural habitat. They tend to hide out a lot in aquariums if provided with adequate vegetation, rocks, and other things. These mollusks can be very social creates as well. It is accustomed to hunting as night, which is when it’s most active.
Natural Habitat
Octopuses can be found in all of the different oceans across the planet. The largest populations of these creatures exist around coral reefs and close to the ocean floor.
Pet Octopus Care Guide
Even a single octopus needs a tank that is at least 55 gallons, as they can grow fairly large. They need a good amount of space for swimming around. It’s also important that you provide your octopus with lots of places to hide. This includes rocks, vegetation and caves.
Common Health Problems
Octopuses are not prone to disease, but they can develop lesions on their skin. It is therefore important that you look out for hard, raised areas on their skin.
Pet Octopus Breeding
When a female octopus lays eggs, it stays with them to ensure they are safe until hatching occurs. The female dies soon after their eggs hatch, leaving the offspring to find their own food without any help whatsoever.
Conclusion
Octopuses are part of the mollusk family and usually grow to about 14-15 inches in captivity.
A bit of biology
Octopuses are members of the Phylum Mollusca, making them the distant cousins of a wide variety of more familiar reef aquarium animals including the Polyplacophorans (chitons), Gastropods (snails & slugs), and Bivalves (clams & mussels).
Housing an Octopus
OK, having gotten that out of the way, let’s move on to discussing what are the needs for keeping an octopus happy and healthy in captivity, and why you should not add one to your reef tank. In general, the cephalopods are highly active predators that have an unusually high metabolism for an invertebrate.
Filtration And Appropriate Water Quality
Now we can come back to the issues of filtration and water quality. Most aquarium books that mention octopus at all claim that these animals are extremely sensitive to water quality and cannot survive without reef-quality water conditions (e.g., Haywood and Wells 1989).
An Aside About Oxygen Concentrations In Seawater
The amount of oxygen which can dissolve in salt water depends on the exact salinity and temperature of your aquarium — the table below gives you the values of oxygen saturation (mg/l) across a wide range of temperatures and salinities. Saturation is the point at which no more oxygen can dissolve in the water under normal conditions.
Keeping Your Octopus In Its Tank
As I mentioned above, I generally prefer to use a well-sealed aquarium with an open sump in which to keep the skimmer and filtration, but a carefully sealed tank without a sump can work just as well, provided you have a reasonably large tank (say at least 30 gallons for an octopus whose head is about the size of a mandarin orange) and good filtration.
Flow In An Octopus Tank
Most species of octopuses like a relatively high flow rate, but that also proves problematic for keeping these animals because most people use powerheads in an aquarium to generate flow, but I cannot really recommend that solution for an octopus tank.
Feeding Your Pet Octopus
The last problem that I will mention in detail is feeding of your pet. As I mentioned now several times, I do not consider an octopus a particularly well- suited addition to a reef tank.
Mysterious Yet Graceful
An octopus is one of the most fascinating and rewarding marine creatures you can keep in the home aquarium. Octopuses interest us with their behavior, their ability to learn, their interaction with us, and their incredible shape- and color-changing abilities. They are intelligent creatures and have their own personalities.
How Do They Behave and Interact?
The dwarf species available now are often nocturnal and don’t interact much, but they can be fun to watch under a red light, which is invisible to the little octopus. The medium-size diurnal octopuses generally available are often interactive and can be interesting to observe and fun to play with.
Where Do I Find Them?
Octopuses are available from a number of sources. Local fish stores sometimes carry octopuses, or can at least order them. Occasionally, owners raise hatchlings and sell them publicly, which makes them the best source for tank-raised specimens.
What Species are Available?
It’s common for fish stores and suppliers to offer octopuses with no species identification. They may be listed as “assorted octopuses,” “brown octopuses,” or some other vague term. Sometimes the identification is faulty; dwarf octopuses have been sold as Octopus vulgaris, a much larger species.
Octopuses to Avoid
The blue-ringed octopus Hapalochlaena lunulata is not a choice for a pet octopus. This small octopus is known for its bright blue rings when threatened, a warning that it is about to bite. The blue-ringed octopus carries venom with a powerful nerve toxin for which there is no antidote.
Tank Requirements
As the Cephalopod Care co-moderator on www.tonmo.com, I have had the opportunity to follow well over 100 octopuses through their lives. As octopus-keepers, we have all learned from each other on the “Ceph Care” forums and have had the opportunity to see what works best for successful octopus-keeping.
Some Special Considerations
Locate sources for food before you acquire an octopus, and price the cost of live crabs. You may be surprised at the expense of feeding, considering that you should provide some live food. You will spend much more on food than the cost of your octopus (unless you can catch your own octo food).
