Fish

Where our fish come from, and how they were obtained, is important information to consider when stocking a system. We have three main options: wild-caught, tank-raised, or captive bred. Wild-caught obviously refers to animals that have been captured in the wild and brought into captivity, but the other two terms are not necessarily clear cut. Tank raised means that eggs or larvae have been collected from the wild and raised in captivity, while captive/tank-bred refers to animals that have been reared from egg to adult in a captive environment. Many species are not currently available by any means other than wild collection, and I feel sustainable harvesting can have a positive impact on indigenous people, who make a living capturing aquarium animals while being given a strong reason to protect that environment for the future. Sustainable wild collection for the aquarium trade has the potential to protect our world’s coral reef ecosystems by showing coastal people the true value of their natural resources so they understand the importance of keeping these underwater habitats healthy. If the reefs are healthy, there will be many fish to collect and plenty of work, both for the current generations and those to come. While there are valid reasons for some aquarists, particularly those who have many years of experience or are breeders, to choose a wild-caught animal over a captive-bred one, for the vast majority of us, tank-raised and captive-bred specimens should be our preferred options. These animals are perfectly adapted to aquarium life, used to eating commercial foods and unlikely to harbor disease. They also reduce stress on ecosystems from collection pressure by eliminating the need for all ornamentals to be wild-caught, and they are often considered to be the best livestock available. The number of captive-bred marine ornamental species that aquarists now have access to is constantly growing and not in any small part due to the efforts of dedicated hobbyists as well as nonprofit organizations—such as Marine Breeders Initiative, a breeder’s award program that supports and promotes the captive breeding of marine organisms—and companies, such as Oceans, Reefs, and Aquariums (ORA) and Sustainable Aquatics (SA), which supply our trade with 100 percent, captive-bred fish and aquacultured corals. According to a 2014 list of captive-bred marine fish, approximately 250 species of ornamentals have now been tank-bred, ranging from anemonefish to gobies to seahorses. This certainly does not mean that we regularly have access to every species that has been bred thus far, but the more we support these efforts with our wallets, the better chance we will have of one day being able to choose from hundreds of readily available tank-bred marine fish without feeling limited to a tank full of clownfish. This article is meant to be a top 10 list of captive-bred marine ornamentals currently available, accompanied by information about their life history, care requirements and their respective places in the world of tank-bred fish. I will, of course, have to begin with the most well-known of all captive-bred fish: Amphiprion ocellaris.

By Kenneth Wingerter Most aquarists like variety. This is especially so with new hobbyists. Community tanks — that is, aquaria that display a broad number and diversity of species — satisfy this soft spot for color, form, and habit. Even so, with time and experience, many aquarists develop an interest in a fish or invertebrate of a particular species (or otherwise smallish group). In some situations, an aquatic animal may fit in with a conventional community perfectly; in others, it is best housed by itself. For the latter case, the specimen is best kept (either alone or with like kind) in an aquarium that is specially tailored to suit its needs: a species tank. Single species tanks are hardly boring. In fact, they can be far more unique and visually appealing than the more typical mishmash of species in a community tank. Above all, they afford the keeper an opportunity to create the most happy and healthy home possible for their favorite animal. Why Choose a Single Species Tank Set-Up? A species tank can be set up for either freshwater, brackish, or marine livestock. Though some animals must be kept in a species tank, any animal can be. There are a handful of reasons why one would opt to set up a species tank. These include: The species requires an unusual type of habitat The species is exceptionally timid or delicate The species is exceptionally aggressive/territorial The species is predatory The species prefers to live with large numbers of its own kind (i.e., colonies or schools) The species exhibits slow or highly specialized feeding behaviors

A 50-gallon long tank is a good middle-of-the-road tank. You can start with something smaller, but most people will soon wish they had gotten a larger tank. Substrate. Base sand as substrate can be found in various degrees of coarseness. Keep in mind that larger grains of sand will give more of a textured look and are less likely to be sucked up into the tube when you vacuum the substrate during water changes. Also, while many different colors of sand can be found in stores, natural-looking tan-colored sand provides a more authentic look to what is found in Lake Tanganyika.,Our fish farm in South Florida uses hundreds of 300- to 6,000-gallon outside vaults (large above-ground concrete structures) on 5 acres of land to breed and raise thousands of African cichlids for sale to retail shops all over the United States and in Canada. Many fishkeepers purchase our fish, but how should they house these African cichlids? If you’re keeping Tanganyikan fish, a great way is to try to replicate the environmental conditions of Lake Tanganyika in Africa. Lake Tanganyika is the sixth largest lake in the world by surface area, covering about 12,700 square miles, and it is the third largest by volume (4,500 cubic miles). It is home to about 400 species of fish (some 250 of those being cichlids). The lake’s water chemistry ranges from 7.5 to 9.3 pH, and it has a total hardness of 10 to 12 degrees and a year-round temperature of 76 to 78 degrees Fahrenheit. With depths of up to 4,700 feet, Lake Tanganyika is the second deepest lake in the world. It is mostly surrounded by mountains, except for a small portion on the east side, and it offers both rocky and sandy coastlines. With all of these conditions, it’s no wonder that there are so many varieties of cichlids that have found their own little niches and continue to thrive in Lake Tanganyika. Keeping those conditions in mind and mimicking them on a smaller scale is how we are able to enjoy these beautiful creatures in our homes. To create a Lake Tanganyika biotope, you’ll need to get your tank supplies, set up the tank, wait for it to cycle, add fish and maintain it properly. Begin by obtaining all of the supplies you’ll need to set up a Lake Tanganyikan aquarium.

The receding tide slowly uncovers a vast mudflat and creates a flurry of activity from scurrying crabs, swooping gulls and unusual fishlike animals scampering from newly exposed holes. Some of these little fish awkwardly swagger, moving only an inch at a time, while others seemingly spring forward as if propelled by springboards. These extraordinary fish are mudskippers. Mudskippers are in the Gobiidae family in the Oxudercinae suborder. Of the 10 mudskipper genera, four species are highly amphibious and spend much of their lives on land. Two of the most common genera available to hobbyists are Periophthalmus and Periophthalmodon. Mudskippers are Old World fishes and originate in tropical intertidal mudflats and brackish mangrove estuaries, from the Atlantic Coast of Africa east through the Indian Ocean to the western Pacific. The name “mudskipper” derives from the mudskipper’s ability to use its tail and body for skipping and hopping on land. They also use their muscular pectoral fins in an alternating manner, called “crutching,” to produce a gawky movement resembling a person on crutches. It is simply amazing to watch these fish deliberately exit the water, move to a rock or log, and bask in the warm overhead lighting like a turtle would.
