Types of Aquariums

There are four different aquarium types to choose from and different reasons to decide on one.

Coldwater Aquariums

These are composed of a freshwater environment for fish that are happy with water at temperatures below 70 degrees, usually at room temperature. These can be a simple as a goldfish bowl which many people kept as kids.

Tropical Aquariums

Tropical aquariums are also freshwater but usually needed to be warmed up to simulated environments that the fish species kept naturally live. Temperatures usually range between 72 and 80 degrees and are fairly easy to maintain.

Marine Aquariums

Saltwater, marine aquariums simulate the oceanic environment and are home usually to much more diverse, yet more difficult to look after species of fish. Certain concentrations of salt are to be purchased and mixed with the water and the creatures that live here have very specific parameters for their environment and so equipment needed may vary.

Brackish Aquariums

Brackish is a mixture of a fresh and saltwater environment, similar to that of an estuary where the river meets the sea. There are species of marine life which are adapted to this environment and the specific conditions required for this aquarium type can be difficult to manage.

Types of Aquarium Fish

The selection of fish and aqueous life there is to choose for your tank is of an amazing variety. They all have different temperaments and specific needs and so if you do decide to mix different species together, make sure to get the advice of the pet shop owner as to whether they would live side by side peacefully.

Here are some examples of pet fish favorites and other creatures that can be kept in different types of aquariums:

What Type of Aquarium Makes The Best Fish Tank?

The type of aquarium to go for will depend on your interest in certain types of fish and your budget. Many people buy aquariums fully intending on keeping piranha for example. Since the pet piranhas that are sold are often from tropical, freshwater environments you would need to supply them with an environment similar to that they are adapted to.

This means providing a heater, water pump and filter and other equipment needed to keep the fish tank as close to the natural environment as possible.

PiranhaOther varieties of pet fish, for example, goldfish and mollies, are happy in tepid environments and require less maintenance and less expenditure on equipment is needed to maintain a cold water aquarium.

With saltwater aquariums, more often even more equipment and maintenance than tropical aquariums is required since you will need to provide for a self-contained, balanced ecosystem that needed certain concentrations of salt mixed into the water, it’s the same with brackish aquariums.

Assuming you are a beginner fish pet owner, you are much better starting off with a cold water or tropical aquarium as they are easy to maintain and can still host some beautiful fish. You won’t need to worry about getting salt water concentrations just right, it’s just more about making sure the water isn’t too dirty and is warm enough for the species you keep.

The size of the fish tank you need to buy will also count on a combination of the varieties of fish you decide on, the number of fish you want to keep and the amount of space you have available but the rule to go by is: the bigger, the better!
