in nutrients can induce disease. The majority of diet-related
problems can easily be averted by providing a variety of foods.
Diseases related to deficiencies, including inadequate
protein and vitamins, appear to be the major problem with aquarium
fish. On the other hand, feeding inappropriate food or excessive
amounts of food can also be detrimental. Fatty degeneration of
the liver occurs when fish have too much fat in their diet.
Starvation is one of the most serious problems of aquarium
fish. A refusal of fish to feed for more than several days can
be related to infectious disease, aggression by tank-mates, or
disinterest in the type of food offered. Some species of fish
are specialised in their feeding requirements; it is not uncommon
for them to refuse various foods. Make sure you know what the
fish have been eating before you purchase them.
It is not unusual for a fish to refuse to eat for several days
after introduction to a new aquarium. This should be considered
normal. Generally, within a few days fish will begin eating properly.
If the fish continue to refuse to feed, make sure that this is
not related to aggression from other tankmates. If this is not
the cause, offer some other types of food, including live foods.
In the majority of cases, this will solve the problem.
