Tropical Fish

The tropical fish are kept in temperatures of about 25°C. They tend to be more expensive to buy than cold water fish and are therefore usually kept in better aquariums (which have such equipment as aerators) and often by enthusiasts prepared to give that extra attention that ensures survival If a problem begins in the aquarium, the Tetras will be first to show signs.
Tropical fish tend generally to be less susceptible to build up of ammonia fish. and nitrites—but this could be that they tend to live in better aquariums.

Marine Fish

Marine fish are kept at
varying temperatures depending on their origin. Some marine fish are from tropical areas of the world, while others are from temperate zones and will be kept at lower temperatures. It is safest to ask the dealer for the most suitable temperature for specific fish. The seawater that the fish are kept in can be natural or synthetic. For those who live close to the ocean and want to use it, collect where the water is clear. Always use a non-toxic, non-corrosive vessel and store the water for six weeks in the dark before using. Always have a reserve of water in case of emergency. Artificial seawater mixes are available commercially – follow the instructions carefully.
Marine fish are very sensitive to nitrite and copper levels. The density of marine fish should be of the order of 1 centimeter of fish length to 10 liters of tank volume. This is much lower than for freshwater fish. The hobbyist should consider gaining aquarium experience with freshwater fish before acquiring a marine aquarium, as marine fish are very expensive and mistakes will be costly.
