Fish Tank Habitat – Cold Water or Tropical Fish?
Selecting your fish tank habitat should be the first thing you do before setting up an aquarium. Start selecting a fish tank habitat by thinking about the types of fish you would like to keep.
There are a lot of fish that are suitable for the beginner but the type of habitat you select should be explored before selecting any fish.
There are three main types of fish tank habitats, Coldwater, Tropical, and Marine. Coldwater and Tropical are freshwater aquarium setups and a Marine aquarium is a saltwater setup.
We recommend for the beginner you focus on either Coldwater or Tropical habitat.
A marine aquarium habitat requires special care, time and in most cases expensive equipment. We recommend a Marine aquarium for more advanced fish keepers.
That said, we will focus on the cold water fish tank and the tropical fish tank.
Let’s explore each fish tank habitat:
“Refers to fish species that prefer cooler water temperatures than tropical fish, typically below 20 °C (68 °F). Some examples are koi and goldfish. These species tend to grow more slowly and live longer than fish that live in warmer waters, and are generally felt to be easier to keep…
When kept in a household aquarium, they do not require a heater and are quite comfortable at around 60°F (15°C). Wikipedia”
Because of these qualities, Coldwater fish are the most popular for children and beginners.
Most Coldwater fish are inexpensive to keep and require less maintenance.
Examples of common coldwater aquarium fish you can keep at home are:
Two Spot Barb
Buenos Aires Tetra
White Cloud Mountain Minnow
All of the above are very hardy fish and can thrive in temperatures in the mid-’60s, all can be found in most pet stores.
There are many more options but this is a good list to start from.
Freshwater Tropical Fish:
Are found in tropical climates and typically require temperatures to be around 75-80°F.
Because of their bright coloring, tropical fish are the most popular with fish keepers.
By installing a heater your aquarium can maintain set temperature with minimal effort.
Here is a great list of the many tropical aquarium fish available:
Have a look through the list and consider a few things, habitat, temperature range, aggression, size.
Once you have a good idea of what fish tank habitat and fish species you would like to keep, we can move on to Step #2.
Top Tip: Tip: Because of the differences in temperature ranges Coldwater and freshwater fish are not typically mixed. However, many of the Coldwater species listed above, Barbs, for example, can do very well in both Coldwater and tropical aquariums.
