The secret behind marine fish
Marine fish are not domesticated fish, and will pursue their survival instincts in the aquarium, just as they do in the sea. Marine fish are found in oceans, estuaries, tidal pools or salt marshes. Almost all species of marine fish are caught in nature. Marine fish are more colorful than freshwater fish, but need more care.
Tropical fish generally have very specific temperature requirements. Clownfish are a popular species of marine aquarium fish Compatibility. All marine fish are tanked for a specified period of time for acclimation, in proper water parameters, under specific conditions to allow the easiest adaptation to aquarium life. Marine fish are the hardest of all fish to keep. Most species of marine fish are sensitive to water conditions and do not adapt easily to a new aquarium, it is best to add the fish after the aquarium has been functioning for a few months.
Fish that are reef safe are known to not nip at corals, and also do not usually eat invertebrates that may be kept in a reef tank, such as snails. Marine fish, also known as saltwater fish, require a simulated oceanic environment in the tank. There are approximately 15,000 species of marine fish, many of which are not compatible in the same aquarium. For this reason, the compatibility of different species and genders within species needs to be checked before multiple fish are introduced to a aquarium. Lionfish, for example, may eat gobies and other species, while Clownfish are likely to attack others of the same gender if one of the opposite genders is present. There are lots of differences between freshwater fish and saltwater fish that may not be obvious to the newly aquarist. Marine fish even hardest to keep are tropical marine fishes.
