|- Always inspect a fish before you buy it to
check for any physical damage. Most pet stores do not do this
for you and it is important that you do not start off with a
fish that is already injured. If you bring a new fish into your
aquarium that already has a disease or infection it is likely
to spread it to your other fish.
- Ensure that the different fish you buy are compatible with
each other. Putting incompatible fish together is a common
mistake and will likely result in one eating the other.
- Read as much as you can about the fish you wish to buy
so you understand beforehand the food to feed it and the water
conditions it requires. Temperature is also a major concern
as tropical fish generally have low tolerances when it comes
to water temperature.
- Regularly monitor your fish for signs of diseases.
Many parasitic infections such as whitespot
and velvet disease
have very little signs before it is too late. You will also
need to monitor the activities of the fish because changes
in behaviour can often indicate a health problem.
