Although Choerodon fasciatus probably lives in harems, they tend to be loose in shape and individuals leave a lot of room between themselves and other members of the group. Keep in mind that in the ocean there are endless possibilities for these fish to escape from each other when needed. However, their territoriality can cause problems in the medium-sized domestic aquarium, since escape is limited to areas within a radius of only a few meters, with limited areas of protection and refuge. For this reason, it is better to have only one defense fish per aquarium. To keep a group, it is better to buy at least half a dozen specimens of very small size and place them in an extremely large tank. C. fasciatus is native to the subtropical and tropical waters of the Indo-Pacific. They are found in much of the western part of the Pacific Ocean, with a range that stretches from Taiwan to the Great Barrier Reef in Australia. Harlequins spend most of their day patrolling habitats ranging from the high seas to seagrass beds and reefs in search of food consisting of various invertebrates such as shrimp, crabs, molluscs, sea urchins and starfish. You will also consume smaller fish when the opportunity arises. Size restrictions allow fish to reach maturity to complete their breeding cycle.
Measure all your fish and bring back alive in the water undersized or excess fish. Mussels on the half shell are also very effective in inducing a feeding reaction. Never offer ordinary fodder goldfish, as these quickly lead to malnutrition and diseases of the side line and headlines. Mollies that have become accustomed to salt water and/or are raised in salt water can be used, but defense fish should be weaned off as soon as possible and switch to a more nutritious diet. Most defense fish won`t eat pellets at first, but they will eventually learn to accept them. Try buying a fish that you have seen eating frozen foods. Ask if it is possible to see the flow. Information about the reproductive habits of this species in the wild, not to mention the aquarium, is minimal. Harlequins are protogynous hermaphrodites; All young people start their lives as women and are able to change their sex to male. Research suggests that they form harems and that usually the largest female in a harem develops into a male as it approaches maturity or when the need for a male arises, for example when the male of a harem is a victim of a predator.
Prevention is better than cure – to avoid catching undersized or excess fish, it`s best to stop fishing once you`ve reached your pocket limit. Illegal fishing could include someone who nets into the river, crosses pocket or possession boundaries, catches undersized fish, fishes in a closed area, has more fishing gear in the water than they should, or sells illegally caught fish in their spare time. The Venus defense fish is expected to be one of the most sought-after tablefish in northern Australia. Not only are they sensational food, but they also offer fishermen a solid fight if they depend on proper equipment. The species is also commonly referred to as blue tusks and bones. This comes from the aqua, the blue colored spine and other internal bones of the fish. Many people also mistakenly call them parrotfish. For example, emperors (with the exception of blue-lined emperors) have an individual daily pocket limit of three in all bioregions except the West Coast. They are also within a daily pocket limit for mixed species of five (for all demersals in these bioregions). Blue adults of defense fish inhabit the sandy and debris areas of reef plains and the shallow bottoms of the outer slopes of reefs.
5 in total*. Only 1 tiger, mako, hammerhead shark # or whaler/blue shark. Harlequins have large orbital eyes that move independently, allowing fish to fully assess their environment. Put these properties together, and they produce a fish of striking beauty. Despite their large wild-looking teeth, they are gentle with almost comical behaviors, making them a great choice to add to any pure fish aquarium. The tuskfish, which measure 4 inches or more, may have already turned into males. By buying fish that are 4 inches or less, you increase your chances of acquiring all the females so that you can switch to a male. They should all be used to the aquarium at the same time. As the fish grows, we hope that a harem will develop with a male and a group of females. Although aggression will likely still exist, disputes should be short and minimal, provided the tank is proportionately large. A tank of minimum size would be at least 180 gallons with plenty of visibility and hiding places.
Again, a larger aquarium is always better. Successfully keeping a group of these fish is almost unknown, but with proper research and conditions not impossible. The perfect aquarium exists in the heart and mind of every marine aquarist. When entering the hobby of saltwater aquarium, one dreams of founding an aquarium full of a selection of life – in different shapes, sizes and colors. People who have been setting up their aquarium for years are always looking for the unique specimen that serves as the centerpiece or highlight for their aquarium. For those who have a saltwater aquarium that has only fish, the harlequin defense fish is such a fish. Due to their diet of various mobile invertebrates, they are usually not suitable for a reef aquarium. While corals and other sessile invertebrates would be safe, shrimp, crabs, sea urchins, starfish, small fish and snails are on the menu and would likely be consumed with enthusiasm. Therefore, it is better to keep harlequins with other large, moderately aggressive and territorial fish.
Tangs, angelfish, grunts, eels, balls, and triggers are all acceptable tank companions, provided they are similar in size. Be sure to introduce the defense fish in front of others to avoid territorial squabbles and intimidation. C. fasciatus tends not to be as aggressive as other species and cannot cope well with the constant harassment of an angry tang or angelfish that feels that its territory is invaded. Off the coast, Venus` defense fish like to feed on or around the turn of the tide. These quality fish can be easily caught all year round and like to devour offers of squid, mullet, stakes and other meat bait. Octopuses and crabs also work well on tuskies. Readily available frozen products include fish, invertebrates and gelatin formulas. After all, their diet should consist of shrimp, krill, shrimp, plankton, squid, squid, mussels, silver sides, etc. All foods offered should be cut into bite-sized portions. Several manufacturers distribute various gelatin formulas for angelfish, triggers, tangs, etc., which can be included in the diet.
