How long can aquarium fish live without food?
by
Healthy adult fish can go for a week or two without feeding. However, young fish don’t have the fat stores of adult fish and they cannot go without eating very long. That doesn’t mean you should routinely skip feedings, but your fish can safely be left without food over a long holiday weekend.
Most cold water fish will be fine for one week without food, however tropical fish usually need to be fed more often. There are a few options for keeping your fish fed while you’re on holiday.

Gravel is the better choice for most freshwater aquariums.

Just like you and me, fish need to breathe. To do this, fish draw dissolved oxygen out of the water – without it, most breeds of fish will suffocate. Bubblers add oxygen to your aquarium.
How do I know if my aquarium has enough oxygen?
Aside from actually testing the water for dissolved oxygen, the only indication of trouble will be the behavior of your fish.
Fish will initially react to lower oxygen levels by moving around less. They will swim less vigorously and even eat less often.
Eventually, fish will begin gasping at the surface of the water.
What is best way to oxygenate aquarium?
Increasing water movement is the quickest way to increase oxygen (O2) levels in a fish tank, as it allows more O2 to dissolve and carbon dioxide (CO2) to be released. This can be easily done using an air pump, performing large water changes, manually stirring the water, or placing a fan near the aquarium.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
