FISHKEEPING.
Tropical Marine Aquarium.
Tropical marine aquarium has the highest initial cost because the fishes are far more expensive than freshwater types.
Once set up and stocked, running costs are not prohibitive, but be sure to gain a year or two’s experience with freshwater fishes
before moving on to this aquarium system, as many tropical marine fishes require special care.
Coldwater Marine Aquarium.
Because only a little equipment is required for this aquarium system and the fishes can be collected for free, the coldwater
marine aquarium can be very cheap to set up and maintain. Although coldwater marine species tend to have dull colouring,
their intriguing habits make them just as interesting as tropical fishes. Many species quickly outgrow the tank and should be
returned to the seashore.
CHOOSING YOUR FISH.
Four Important Considerations.
Find out in advance which fishes are suited to your aquarium, and establish whether any species will require special care (such
as being fed live foods). Before buying your fish, take into account the following: aquarium suitability, physical health, ease of
care, and compatibility with other fishes.
Selecting Hardy Stock.
Start off properly by picking the hardiest stock for your aquarium tank. This is most important if you are planning your first aquarium
because it will take time for you (and your fishes) to become accustomed to your routine. Also, you fishes must be hardly enough to
survive any troubles that may arise as a result of your lack of expertise expert handling until you have gained sufficient experience.
What to look for in a fish?
Before purchasing a fish, check that it swims effortlessly and that it easily maintains it position in the water.
* If possible, check that the fish you wish to purchase is eating food readily.
* Fins of freshwater fish should be erect.
* The colour of the fish should be dense; where a pattern is formed there should be no blurring of adjacent colours.
* In species where the colour patterns are a special feature, patterns should conform to the expected “standard”.
Unhealthy Fish.
The best way to avoid buying an unhealthy fish is to recognize the outward signs of illness.
* Generally, avoid a fish that sulks in the corner of the tank, although it may be a species that is naturally shy.
* An unhealthy fish may swim with its fins held flat against its body.
* A fish suffering from an internal aliment may trial colourless excreta.
* Don’t choose a fish with boils, spots, lumps, open wounds, or split fins.
* Never buy a fish from a tank that contains dead specimens.
Jetlagged Stock.
A fish may have travelled for thousands of miles before reaching your local aquarist. A good dealer will often recommend that
you do not buy new arrivals straight away, as they may die from disease or stress. The dealer will be happy to reserve the fishes for you.
Considering the Size of your Fish.
Always try to find out what adult, or maximum aquarium, size a fish will attain before you buy it. The fish will attain before
you buy it. The fish may appear to be just the size you want in the dealer’s tank, but bear in mind that the fishes are all juveniles, and
their eventual size will be at least double their present size and possibly larger still.
compatible Companions.
It is vital to select compatible fishes for your aquarium. Many species naturally school and can become bored or aggressive if they are kept
in a tank without another of their own species. On the other hand, some fishes, which are happy to share tank space with different species of
fish, will not tolerate the company of their own species.
Feisty Fish.
Be sure that you do not introduce a carnivorous fish into your aquarium or you will soon notice the disappearance of all your smaller fishes.
Any carnivorous species should be kept in a tank on their own or else in a communal aquarium with other species that are a similar size.
Filling The Tank.
to make full use of all of the space in your aquarium, select a range of species to occupy the different levels of the tank. Not occupy the
different levels of the tanks. Not all fishes have the same habits; some are better adapted for feeding from the water
surface, others cruise about in mid-water, while a third group rarely leaves the floor of the tank. by selecting fishes from each of these levels
you can make full use of every bit of water depth in your tanks.
Considering Lifespans.
When stocking your aquarium tank, it is worth considering the fact that not every fish lives to the same age. Coldwater freshwater fish tend to live longest -
some Koi and Goldfish live for over 20 years. Some species are naturally short-lived. killifish, for example, may only live for a year. in general, the
larger the fish, the longer it will live. Avoid buying fish with a humpbacked appeareance uncharacteristic of the species.
The deformity is a typical sign of old age.
