Octopus fish

If you’ve never had an octopus before, you may be completely oblivious to the animal’s care requirements. So, let’s go through the basics to figure out the core facts about this awesome creature: • All octopi are carnivorous – They will consume a variety of fish and crustaceans even larger than their bodies. This means you can’t really pair them with any tank mate. These are solitary creatures that need to live alone and undisturbed in their environment. • Temperature requirements vary dramatically – The octopus demands varying temperature ranges, depending on the species. In this sense, we have 59 to 72 F for the California two-spot octopus, 74 to 76 for the Caribbean dwarf octopus, and 60 to 65 F for the East Pacific red octopus. • Escape artists – The octopus is highly intelligent and will escape even from seemingly secured habitats. No matter how large their bodies are, they can always squeeze it through crevices and holes as big as the octopus’s eye. • Very aggressive – You cannot keep more than 1 octopus in the same tank. They have no patience for any tank mate and have no social instincts. These animals are particularly aggressive towards their own and will resort to murder and cannibalism if you force them to live together. Now, let’s look at some good octopi species that you can keep as pets. Pet Octopus You Can Keep in Aquarium While it may sound intimidating, keeping and caring for a pet octopus isn’t too difficult. You only need to consider the animal’s basic r...

So You Want to Keep an Octopus… Author: Nancy King Octopuses exhibit intriguing behavior, surprising intelligence, and incredible shape- and color-changing abilities in the aquarium—as well as tragically short lifespans. 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. If you’re willing to take some time and effort, and you can afford shrimp and crabs for food, then maybe you’d like to consider keeping an octopus. Drawbacks Some of the negatives of octopus-keeping include the short lifespan (less than a year for most), high cost of food, tendency to hide or remain camouflaged when you most want to see them, and the very restricted list of possible tankmates. You probably won’t be able to keep your favorite fish and corals in the same tank with the octopus. It’s also difficult for reef-tank owners to give up the sophisticated equipment (metal halide lights, UV filters, wavemakers, etc.) that are unnecessary and undesirable for an octopus. Simple Tasks Octopus-keeping can be easy in that they only need simple wet-dry filtration, don’t require much light, and don’t demand many of the precise conditions that sessile reef invertebrates need. Challenges There are also several challeng...

It contains no fiber or sugar. Omega-3 fatty acids are found in certain plants as alpha-linolenic acid (ALA). In fish and other seafood, the omega-3s are in the form of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Your body only uses EPA and DHA to perform essential functions, including those that benefit heart health. ALA is converted to EPA and DHA in your liver, but the conversion is inefficient. ALA is the primary source of Omega-3 fatty acids in the American diet, so there is a need for EPA and DHA, which octopus provides. The recommended adequate intake for omega-3 fatty acids ranges from 1.1 to 1.6 grams per day. Supports Immune Function Your immune system relies on a number of essential nutrients to run efficiently, including some nutrients in octopus like protein, zinc, selenium, and vitamin B12. No food provides everything your body needs, but octopus can provide you with many of the nutrients it needs to support your immune system when combined with other nutrient-dense foods, getting enough sleep, and other healthy lifestyle factors like stress management.

I love grumps. Oscar the Grouch is my favorite Sesame Street character. I’m obsessed with Grumpy Cat. I love the perpetual frowns of the This is why in December 2020, it felt like the science community gave me a gift. They revealed there was a new top grump of the ocean: the octopus. Apparently, octopuses also have an occasional bad day and when they do, they punch fish. You read that right, there is now scientific evidence that octopuses punch unsuspecting fish for no known reason. When I first saw this pop up while I was scrolling my feed, I immediately thought it was fiction. But with a quick search, I found the gloriously named paper titled Octopuses punch fishes during collaborative interspecific hunting events . Sure enough, researchers were studying hunting parties that include a variety of different fishes. Octopuses are generally solo creatures but they’ll join these parties to help find prey. Think of these hunting parties like the Avengers. Each species has its own skillset and with their powers combined they can defeat Thanos … or in this case, find a tasty meal. For instance, a grouper finds prey it can’t get to in a crevice. They will While researchers were watching these hunting parties, they noticed that octopuses would occasionally punch their fellow party mates. Sometimes the researchers could see the cause for the punch. The octopus wanted the fish to get away from its prey or needed to redirect the fish. But occasionally they didn’t see a reason at all....

These brainy cephalopods sometimes team up with fish to find food; hunting collaboratively like this allows them to cover more area, and it increases their chances of catching prey. However, when big blue octopuses ( Octopus cyanea), also known as day octopuses, are displeased with their fish partners, they demonstrate their ire by suddenly punching the fish in the head. The octopus lashes out using "a swift, explosive motion with one arm," in an attack "which we refer to as punching," scientists wrote in a new study. Sometimes, fish and octopuses will work together for more than an hour, with different species scouting different locations. Octopuses pursue prey that dart around rocks and into tight spaces in the reef, while bottom-feeding fish such as the yellow-saddle goatfish ( Parupeneus cyclostomus) scour the seafloor, and other fish species patrol the water column, according to the study. But those collaborations don't always work out so well for the fish, the new study shows. Between 2018 and 2019, researchers observed eight incidents while diving in Eilat, Israel, and in El Quseir, Egypt, in which octopuses suddenly punched out their supposed partners. "I laughed out loud, and almost choked on my own regulator," said lead study author Eduardo Sampaio, a Ph.D. student at the University of Lisbon and the Max Planck Institute of Animal Behavior. His later reactions were more subdued, "but I still marveled at it every time I saw it," he told Live Science in an email. "...

Keeping fish, crabs, shrimp, or other sea creatures in an aquarium can be pleasant and rather effortless once you have the system under control. However, with an octopus, you kick the difficulty up a notch and introduce a new layer of challenges to the aquarium. Suffice to say; keeping an octopus in an aquarium not easy. These intelligent sea animals don’t have the same needs as the everyday aquarium fish. They require special care that novice fish keepers might overlook. Nonetheless, octopuses are rewarding to keep and have a fascinating personality unlike any other. Plus, they’re super fun to observe! Octopus keeping doesn’t have to be hard. Let’s explore the ocean depths of keeping an octopus safe and happy in the aquarium. Table of Contents • • • • • • • • • The Aquarium: Conditions, Temperatures, and Habitat Octopuses are naturally solitary creatures, so they fare well in isolated tanks in the right environment. These are the conditions that your aquarium should ideally meet for your octopus keeping needs: • A sealed lid to prevent an imbalance • A salinity between 1.022 – 1.023 • pH values of 8.2 with sufficient oxygen flow • 76-78 degrees Fahrenheit • For one octopus, at least 55 gallons of water Outside the aquarium, keep your octopus in a dimly lit environment. Don’t put them in a room that has exposure to direct sunlight. During the day, use dim light from a low wattage fluorescent tube; and at night, turn off any light source that may irritate your octopus. As f...
