Choosing and buying your goldfish
There are many varieties to choose from ranging from the common goldfish
to varieties such as: comets, fantails, orandas, lionheads, shubunkins and
moors.
The varieties can be mixed but all fish should be of a similar size and be
compatible for water temperature and feeding habits.
A healthy goldfish should:
swim easily through the water and be active
not gasp at the surface of the tank or swim in a peculiar manner
have scales that cover the body evenly without any cuts or growths
Housing
Your indoor aquarium should be set up at least one week before introducing
any fish to allow the water and filtration system to mature.
INDOOR AQUARIUM
There is a great variety of designs and sizes to choose from. Always select
a branded product. Handle with great care and transport horizontally. The
tank must be placed either on a specially designed stand or a strong rigid
surface with an expanded polystyrene mat underneath the tank. Remember
that a full tank is heavy. Position the tank away from windows as daylight
encourages algae growth. Never move a tank containing water.
SETTING UP YOUR TANK
Thoroughly rinse your new tank with clean water. Cover the bottom with
carefully washed gravel. You may also wish to add some aquatic
ornaments, rocks and plants. Plants will need to be trimmed regularly.
Always use a water conditioner to make the tap water safe. Introduce the
fish only when the water quality is suitable. Your retailer will advise you on
the number of goldfish you should keep in your chosen set-up. A filtration
system is always recommended.
WATER CHANGES
Always use conditioned water. For systems with a filter, carry out regular
25% water changes, with a complete change when necessary. For systems
without a filter, change half the water weekly and a complete water change
every month.
POOLS AND PONDS
The ideal pond should be at least 2ft (60cm) deep with as big a surface area
as is practical. Deep ponds will help the fish to survive hard winters. Large
ponds are more likely to achieve a natural balance of plant life that will
enable the fish to survive and flourish with the minimum of attention. A large
volume of water has a more stable temperature which is beneficial to the
fish. Plants help to provide cover and assist oxygenation. They also convert
fish wastes which assist with their natural growth. Do not overstock or
overfeed. Plants should be thinned out if the cover exceeds 30%.
INTRODUCING YOUR FISH INTO THE TANK
First turn the tank light off as this helps to reduce stress. Float the unopened
bag in the top of the tank for at least 15 minutes to regulate any temperature
differences - this avoids shocking the fish. Open the bag and allow the tank
water to enter it before gently releasing your fish into the tank
. Turn the light
back on after 2 hours.
Feeding and Water
Aquarium Fish
- Feed daily according to the manufacturers instructions.
Never overfeed.
Pond Fish
- Feeding may be necessary only every other day, and still less
frequently in winter. Feed according to manufacturers instructions. During
the summer there is likely to be natural food.
Handling
Handling fish should be kept to a minimum and cause as little stress as
possible. Use a net to catch the fish. Gently corner the fish and then catch it
quickly. Place the fish gently in a holding receptacle that contains water from
the tank.
