How long can fish survive without filter?
by
A fish live without a filter for a maximum of seven days and a minimum of three days. A filter helps clean the water over and over again, so the toxins in it don’t settle down. But that doesn’t make the filter a necessity for fish survival.
For example, live aquarium plants will act as filters by converting the CO2 produced by your fish into the oxygen they need to breathe. Having plenty of live plants in your unfiltered tank will help to keep the water quality in your tank high enough for your fish to survive.
Do fish actually need a filter?
All fish tanks MUST have biological filtration; biological filtration is the cheapest, most efficient and most stable way to breakdown toxic ammonia. Mechanical filtration traps such particles as plant leaves, uneaten food, etc., allowing them to be removed from the tank before they decompose into ammonia.
An aquarium fish can stay up to two days without oxygen (in still water) but they still need some more amount of oxygen to breathe and do their essential daily work.

How do I know if my fish 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.

How do you oxygenate water quickly?
Oxygenation can be achieved with several types of aeration equipment:
Oxygen Saturation Technology (OST) A new and exciting industry innovation is Oxygen Saturation Technology (OST).
Submersed Aerators. Submersed aerators, on the other hand, provide aeration through circulation.
Floating Fountains.
Nanobubble Technology.
Can fish recover from lack of oxygen?
Gill remodelling in hypoxia
As a response to hypoxia, some fish are able to remodel their gills to increase respiratory surface area, with some species such as goldfish doubling their lamellar surface areas in as little as 8 hours.
“Gasping” or “piping” is the term for when your fish is rapidly breathing at the water surface, often with part of their mouth above the surface. This is most often a sign that your fish isn’t getting enough oxygen.
How do you increase oxygen in fish?
Does cold water hold more oxygen?
Cold water can hold more dissolved oxygen than warm water. In winter and early spring, when the water temperature is low, the dissolved oxygen concentration is high. In summer and fall, when the water temperature is high, the dissolved-oxygen concentration is often lower.
Are air bubbles good for fish tank?
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.
Do air stones add oxygen to water?
Before purchasing an air stone, it’s important to understand what its purpose is. First, they provide oxygen to the water and diffuse large bubbles. In addition, they can reduce the noise created by the filtration system. The reason they’re useful in aquariums is that they’re cheap and easy to use.
