FK Primers: Coldwater, Tropical and Marine Aquariums
Published by Fishadmin on 1/3/2009 (15101 reads)
This article introduces the most common types of aquarium kept in the UK, briefly explaining the difference between freshwater and saltwater systems and which may suit your level of skill and budget.


Freshwater Aquarium

A freshwater aquarium is a tank that contains water similar to the water found in the majority of rivers and lakes in the world. The two types of freshwater aquarium commonly kept in the UK are known as coldwater and tropical.

Coldwater
A coldwater aquarium generally doesnít contain a heater. The tank water will be near to the temperature of the room. If the room temperature isnít stable you may need a heater to compensate for temperature changes. Coldwater fish include the White Cloud Mountain Minnow and goldfish varieties such as the Comet and Fantail. Coldwater fishkeeping is sometimes recommended as the best option both for beginners and those on a budget but it should be noted that all goldfish varieties will need substantially bigger tanks than many tropical species.

Tropical
A tropical aquarium contains a heater to keep the water temperature at the level required by the inhabitants. Different species will require specific temperatures. There are many types of tropical fish to choose from but care must be taken to choose fish that are compatible with each other and the water chemistry of your tank.



Saltwater Aquarium

A saltwater aquarium is a tank that contains water similar to the water found in coastal and ocean areas of the world.

Marine
The most common type of marine tank in the UK is a tropical marine tank. Like the tropical freshwater systems these tanks require a heater to keep the temperature near to those found in nature. Marine aquariums are more difficult and expensive to keep than other aquariums due to the complexity of water chemistry and the extra equipment required.

Brackish
Brackish aquariums recreate the environment found in estuaries and other parts of the world where the water contains salt levels somewhere between freshwater and marine environments.

 marine coldwater aquaria
I am looking for expert guidance.
Years ago I kept a cold marine aquarium. It was beautiful. I know how to construct a sustainable aquarium with gravel filter etc.
I always felt that the rock pool flora and fauna couldn't cope with this environment. The prawns, anemones, Blennies rapidly succumbed. A hermit crab escaped from the aquarium and died on my bedroom floor!
They did not have the rock pool environment they needed. Yet I would like to improvise a rock pool in an aquarium. How could one reproduce tides?
Would having a shore profile in the aquarium suffice? Letting them go up and down the shore as they wanted. Would that work?
Thanks
Liz
