PropagationPlants have several means of reproducing. Some species reproduce amazingly fast, taking over an entire tank in a matter of weeks, while others do not appear to propagate themselves at all. |

ReleasingAfter being held captive, a turtle, even a native species, should not be released into the wild unless checked by a vet or rehabilitation specialist. The turtle may not be able to recognize and capture natural prey and may introduce disease into the wild population. Captive turtles may lack adequate immune systems to survive a sudden release, as is common in turtles housed in sterile, indoor tanks. |

Salmon as foodSalmon is a popular food, and reasonably healthy due to its high protein and Omega-3 fatty acids and its overall low fat levels. According to reports by Science, however, farmed salmon may contain high levels of dioxins. PCB (Polychlorinated biphenyl) levels may also be up to 8 times higher in farmed salmon compared to wild salmon, and Omega-3 content may also be lower than wild caught species. But according to the British FSA (Food Standards Agency) the benefits of eating even farmed salmon still outweigh the risks. Conversely, salmon is generally one of the least tainted by methyl mercury of all fish. |

Secondary water characteristicsSecondary water characteristics are also important to the success of an aquarium. The temperature of the water forms the basis of one of the two most basic aquarium classifications: tropical vs. cold water. Most fish and plant species tolerate only a limited range of water temperatures: Tropical or warm water aquaria, with an average temperature of about 25 °C (78 °F), are much more common and house most popular aquarium fish. Cold water aquaria are those with temperatures below what would be considered tropical; a variety of fish are better suited to this cooler environment. |

Seeding a new tankSeeding is the process of using gravel from an existing tank to jump start the bacterial colonies in a new tank. If you know you are going to start a new tank, take a filter bag, fill it some gravel you plan to use in the new tank, then put the bag in an established tank for a few weeks. When you get the new tank set up, transfer the bag of gravel into it, and you have built in bacteria. Don't have a filter bag? No problem, use clean panty hose instead. |

SizeAn aquarium can range from a small, unadorned glass bowl containing less than a liter of water—although generally unsuited for most fish (except, perhaps, air breathing fish such as Betta splendens)—to massive tanks built-in public aquaria which are limited only by engineering constraints and can house entire ecosystems as large as kelp forests or species of large sharks. In general, larger aquarium systems are typically recommended to hobbyists due to their resistance to rapid fluctuations of temperature and pH, allowing for greater system stability. |

Skin or Gill FlukesSkin or Gill Flukes are tiny worm-like parasites that are invisible to the naked eye. They attach to fish with hook-like structures and while attached can actually move around. As with many parasitic organisms, fish are not likely to be affected unless they are stressed or sick. They affect mainly young fish, older fish seem to be less |

Source of aquarium inhabitantsFish and plants for the first modern aquaria were gathered from the wild and transported (usually by ship) to European and American ports. During the early twentieth century many species of small colorful tropical fish were caught and exported from Manaus Brazil, Bangkok Thailand, Siam, Jakarta Indonesia, the Dutch West Indies, Calcutta India, and other tropical ports. Collection of fish, plants, and invertebrates from the wild for supply to the aquarium trade continues today at locations around the world. In many places of the world, impoverished local villagers collect specimens for the |
