Saltwater Aquarium Information.

All fishes found in the big sea or oceans are saltwater fish. The water is salty, thus we call it "saltwater".
Most of the fish you see in popular public national aquariums are saltwater fish (marine fish).

These fishes are more colourful and varies greatly in colours and shapes, making them
interesting to watch and observe. It is also a big challenge to keep marine fish
because of their fragility. If you succeed, there is a great sense of accomplishment and of course
visual enjoyment.

Being used to living in oceans, marine fish have very limited abilities to adapt to changing water conditions.
When the water volume is as huge as the ocean, the chemical composition and water quality is almost constant.
With no need to adapt to changes, marine fish are very sensitive fish.

Imagine adding a drop of fruit syrup in a cup of water- you can detect a slight taste when you drink it.
Now add the same size drop of syrup into a large water bottle- the taste is undetectable because it is dispersed too much.
In the same way, in a small fish tank, the waste produced by the fish changes the water quality easier.
Contrasting to public wrong opinion, therefore, it is easier to keep fish in larger fish tanks than
smaller ones. If you are a beginner fish keeper, and expecially if you really have to start with
saltwater fish, I highly recommend you to get as large a tank as you can afford to. However,
I will strongly advise you to keep freshwater fish before going marine, because freshwater
fish are more forgiving and will give you more leeway in your learning foundations.

   Getting Started   

It is very important to start on the right foot in keeping marine fish. One reason is that they are more fragile and sensitive than freshwater fish in the home aquarium setup. Another reason is they are much more expensive!

Setting up new marine aquarium
Tips from a bro who have been keeping marine fish for 19 years and in the trade for 2.5. This section covers 1) Tank & initial setup 2) Filtration & Water Tests 3) Lighting 4) Temperature 5) Livestock and lastly Maintenance.

Cycling a new marine aquarium
Before you even aquire your fish, you should make sure that your fish tank is cycled first. This is especially important for marine fishes that do not adapt to changes in water parameters.

Add new marine fish to existing aquarium
Properly introducing a new marine fish to its tankmates can make the difference between life and death. If this stage is not done properly, the new fish will be very stressed and can fall sick and possibly die. Marine fish are naturally found in huge water bodies, and putting on in a fish tank already gives them a lot of stress. Whereas we cannot avoid this space constraint stress, we can reduce other stress factors.


 Water additives

Due to the great difference between saltwater and household tap water, adjustments have to be made to make the tap water as close to sea water as possible. Often, the most tricky part in marine aquaria is adjusting the water. This is also the part that many new hobbists make the mistake; many newcomers to the hobby tend to use normal tap water, which will not kill marine fish outright, but they will not live for long..

In this section, you will learn you can add to the water to imitate seawater.

Test kits are essential when keeping saltwater fish.

Some explanations of water parameters you need to keep track of.


   Marine Fish Nutrition

Marine fish need species specialised diet. Unlike freshwater fish, you cannot feed the same food to the whole community tank.


 Fish diseases

As all living things live and die, sickness and diseases are part and parcel of life. This can cost you a great deal with expensive marine fish. In this section I will teach you how to recognise the most common marine fish diseases, as well as how to fight them.


 Breeding Fish

It is a huge challenge to breed marine fish! I have not bred marine fish successfully before, so these are just some information which you can look at.
