MARINE FISH

There are almost 20,000 species of marine fish in the world, but only a small minority is of any interest to the aquarist. Of these, most come from the Pacific and Indian oceans, although a few are native to Australia and the tropical Atlantic ocean. Marine fish are usually collected in their natural environment and rarely reproduce in captivity. They find it more difficult to acclimatize than freshwater fish, particularly as regards feeding: some refuse to eat artificial food, and others have very special dietary requirements. The smallest marine fish require a minimum water volume of 150-200 liters. Medium-sized species (around 20 cm) must he kept in tanks of 300 liters, or at least 400 liters if they are active. It is advisable to obtain juvenile (or sub-adult) specimens, as they are generally easier to acclimatize and feed.
