Hence, it’s hard to keep track of the population of these cuttlefish.Where does a dwarf cuttlefish live?In the wild, dwarf cuttlefish (Sepia bandensis) are found in the waters of the Indo-Pacific range. They can be seen near the coasts of Alas Strait, Borneo, Sulawesi, Philippines, Java, and New Guinea in the waters of the Banda Sea, Celebes Sea, Arafura Sea, Flores Sea, and the Sulu Sea. A number of them have also been seen near the northeast range of the Marshall Islands and the northern range of Australia.What is a dwarf cuttlefish’s habitat?Dwarf cuttlefish are demersal fish. Demersal fish are ones that live on the ground. Dwarf cuttlefish are found in shallow waters, mainly in waters with an abundance of sand and coral reefs. Many also live in households as pets around the world.Who do dwarf cuttlefish live with?In nature, dwarf cuttlefish (Sepia bandensis) are found living with sea stars and sea cucumbers. If you keep them in tanks, we recommend not to keep them with other fish. In most cases, they will end up eating each other. The best tank mate for them is harmless corals.How long does a dwarf cuttlefish live?This cephalopod doesn’t live very long. They live for only about a year or so.How do they reproduce?The breeding season of the dwarf cuttlefish is not known. The female and the male cuttlefish of the species mature sexually when they are around five months old. They are known to be gonochoric, which means that individual sex is genetically determined and does not change throughout their lifetime. As the breeding time arrives, males will display a number of courtship rituals to attract a mate. If the display is successful, the copulation can last from a few seconds to a few minutes. The gestation period of these cuttlefish is known to be around a month. After that, the female lays about 8-40 eggs. These eggs are laid attached to various things on the ground, and each cuttlefish egg is laid one at a time. As time goes on, the eggs grow in size and become transparent from their previously purplish to black color. The hatchlings are known to grow up at a fast pace.What is their conservation status?The conservation status of the dwarf cuttlefish, according to the International Union for Conservation of Nature or the IUCN in their Red List, is listed as Data Deficient.

They also have three hearts, an ink sac, and blue-colored copper-based blood. They are known to have 360-degree vision, but they are color blind. They have fins and a cuttlebone to help with swimming and beak-like jaws. They are greenish-yellow brown to light brown in color with mottled patterns of white. On the rear of their mantle, a pattern of a couple of brown patches can be seen. They have color-changing abilities where they can even change the color pattern of their bodies according to their mood. This helps them camouflage.

This helps them express aggression, danger, sexual willingness, and more. They also squirt ink to ward off predators.How big is a dwarf cuttlefish?Dwarf cuttlefish grow up to about 4 in (10.2 cm) in size. They grow at a fast pace. A baby cuttlefish is less than 0.2 in (0.5 cm) in size but grows up to 1 in (2.5 cm) in two months and reaches full mature size within six months. They are about six times smaller than octopuses, who are about 24 in (61 cm) in size.How fast can a dwarf cuttlefish swim?This cephalopod doesn’t swim much.

They mainly feed on fish or crustaceans, like shrimp or crabs. Whenever a shrimp or any crabs get close, these cephalopods deceive them with the help of their color-changing abilities and then grab them with a quick reflex. It will shoot its feeding tentacles to grab its prey and take it in. Their beak-like jaws do the rest of the work pretty quickly. Hatchlings, on the other hand, can’t hunt when they are young. If you’re captive breeding, then you can feed them live food, like shrimp, specifically the Mysis shrimp. Try to avoid feeding them any brine shrimp as it can shorten the lifespan of the cuttlefish.Are they dangerous?These cephalopods are not dangerous or aggressive towards humans. Many people keep them as pets for this reason. They are predators, though, so they pose some harm to a few aquatic animals.Would they make a good pet?They make excellent pets. However, you need to remember a few things if you want to keep them as pets. The tank size for a single dwarf cuttlefish should be at least 30 gal (136.4 l). We suggest to up the tank size from there if you want to keep a number of them together. The water should be clean with extremely low levels of nitrate and zero levels of nitrite and ammonia. Preferably with a pH of 8.0-8.5, and a temperature of 78°F (25.6°C). 1 in (2.5 cm) of sand can be the perfect substrate for them. They don’t require too many lighting conditions; rather, simple fluorescent lights will work well for them. We would suggest you keep the water flow more in the tank than less. Cleaning the tank frequently would be necessary for these cephalopods are known to scatter a lot of water after they eat food, like shrimp or crabs.Did you know…The way dwarf cuttlefish (Sepia bandensis) die is a tragic story. They go through a phase which is known as senescence. During this, they lose their sense of coordination and lose their ability to swim, and see. Hence, they can’t hunt or can’t eat food even if the food is present before them. In this state, they don’t live long in the wild, as they soon get hunted by predators.At around three months of age, the male cuttlefish start to display other male cuttlefish by changing their skin color to black and white patterns, elongating their body size, and flailing their arms.These cephalopods have the ability to disguise themselves as members of the opposite sex, which comes in handy for males of the species to attract females for mating. The males change their body color and disguise themselves as females. This helps the males pass through many places. This also impresses the females and increases the chances of mating for the males.What’s special about the dwarf cuttlefish?The most special thing about the dwarf cuttlefish by which you can tell them apart lies in their appearance.
