Freshwater fish tanks aquariums are sub-divided into planted tanks, cichlid
tanks, brackish tanks, predator tanks among others. Saltwater fish tank
aquariums are also divided into three sub-categories known as fish-only,
fish-only with live rock and reef tanks.
It is important to start to understand the only real main difference between
freshwater fish and saltwater fish. As the names suggest,
freshwater fish exist in
fresh water while for
saltwater fish, their environment is the
sea. In the end your selection of tank is largely based on personal preference
and budget; however, this article gives some additional information to
factor in when making the decision to purchase your next tank.
1. Freshwater tanks are the easier than saltwater to maintain. Keeping
saltwater fish and maintaining a saltwater aquarium definitely requires
much more effort and money than freshwater so if your new to aquariums
a freshwater aquarium would be a inexpensive and easy first tank.
2. Freshwater fish are also not as expensive to purchase. Keeping fish
successfully is a learned porcess and primarily done by trial and error
so unless budget is of no concern you probably do not want to trial and
error with costly fish.
3. Freshwater fish have no problems breeding in tanks and should probably
be your choice of tank if you are looking to breed fishes. Saltwater fishes
have very stringent breeding requirements and very few have been successfully
bred in captivity.
4. In regard to environment, you’ll find freshwater fish are way
more resilient and forgiving through mess ups to their environment than
saltwater fish are. When you are first starting out getting the proper
chemical balance in a tank can be challenging, freshwater fish are hearty
and much more likely than saltwater fish to live through dramatic shifts
to the chemical environment in their tank.
5. Water for freshwater fish tanks usually comes direct from your home
tap, and salinity of tap water is never suited for you to rear saltwater
fish.You also need to treat the tap water before it goes into your freshwater
fish tanks aquariums, but the effort and steps require are less than that
of saltwater tanks.
1. Freshwater fish are less vibrant and color however to be fair there
are some actually gorgeous freshwater exotic fish available for you to
select for your aquarium.
2. Freshwater fish tanks aquariums can get very expensive if you set up
demanding tanks like planted tanks. The large amount of plants in the
tank requires a lot more lighting and fertilizers. These can be more expensive
than your fishes and make your freshwater tank more expensive than saltwater tanks.
1. Saltwater tanks undeniably get an edge over freshwater tanks in terms
of the variety of fishes and the colors they can add to your fish tanks
aquariums! Saltwater tanks can contain many invertebrates like shrimp,
crabs and corals, which freshwater tanks lack.
2. Saltwater tank can be even more colorful with the addition of corals.
Freshwater tanks can also be quite colorful if you rear tropical freshwater
fishes, but even then, nothing much comes close to a reef tank when you’re
talking about color and variety.
1. Saltwater tanks require you to treat the water specially to achieve
the correct salinity and to maintain them in that way. Maintaining freshwater
fish is far easier than maintaining saltwater fish. This is particularly
true in terms of tank water chemistry where the fish owner has lots more
to handle. Then you’ve got the salt water mix to be troubled with.
2. Saltwater fish cost a great deal more than the freshwater fish do. Most
saltwater fish are caught in natural habitats while the freshwater fish
are bred in captivity. Saltwater fishes tend to cost more than freshwater
fishes because they are more difficult to acquire and also costs more
3. With respect to size the saltwater fish definitely need the larger tanks
compared to freshwater fish. If you have space issues and budget constraints
you might want to rethink choosing a saltwater aquarium.
4. Some of us here may like to breed fishes of your own in your fish tanks
aquariums, but saltwater fishes have very stringent breeding requirements.
Most of them breed during seasonal changes when tides or temperature vary.
But this is difficult to create in a tank environment; therefore saltwater
fishes rarely breed in captivity.
