A marine aquarium is for keeping marine fish and plants. The keeping of marine fish goes back to
Roman times. The Romans kept anemones in jars made out of Venetian glass.
Nowadays to keep a marine aquarium shouldn’t take real science but they are considered to be
more difficult to keep than freshwater aquariums, and require slightly higher maintenance.
You might wonder why have a marine aquarium? But the answer is simple, Marine aquariums enable
you to keep and breed a wide range of fish not usually available in freshwater aquariums, and also by the vivid
colors of the marine fish.

Water is the most important factor in having a successful marine aquarium. Marine water
parameters are different from freshwater. The saltwater that you put in your marine aquarium has to be prepared;
you can’t just take the water from the sea or ocean, as it is full of micro-organisms that could kill your
aquarium fish. The water salinity must be perfect for the fish, otherwise they
Marine fish are very sensitive to environmental changes, and could die if the temperature is
unstable. It is recommended that before you set up the aquarium you invest in a test kit that allows you to keep
track of water’s pH, alkalinity, water hardness, and ammonia, nitrite and nitrate levels. The key to a successful
marine aquarium is simply to keep the water’s parameters stable. You should also know that marine fish are happiest
in big environments so try not to squeeze too many into a small aquarium.
Types of marine aquariums
Marine aquariums are sub-divided into aquariums with fish only (FO), fish only with live rocks,
and aquariums with reef aquaria.
Live rocks are composed of limestone and decomposing coral skeleton, the Rocks themselves are
not actually alive, but there are microorganisms that live on them are. Live rock can house bacteria, tiny
organisms, snails, sea urchin, and sea sponges. When you set up the aquarium they may
not reveal themselves, but should appear within a few of being introduced to their new environment. Live rocks are used to recreate the fish’s habitat and are very useful in cleaning the
Reef aquaria are made up of many types of coral and reef invertebrates, and also recreate the
fish’s natural environment.
Good Luck with the setting up of your marine aquarium.
