What are the signs of a fish dying?

Weakness or listlessness. Loss of balance or buoyancy control, floating upside down, or ‘sitting’ on the tank floor (most fish are normally only slightly negatively-buoyant and it takes little effort to maintain position in the water column) Erratic/spiral swimming or shimmying.

What causes septicemia in fish?

Viral hemorrhagic septicemia (syn. Egtved) is a systemic infection of several salmonid and a growing list of marine and freshwater fish that is caused by viral hemorrhagic septicemia virus. The infection may occur in fish of any age, resulting in significant mortality, and fish that survive may become carriers.

Why do my fish seem to be gasping for air?

The reason they are at the surface trying to breathe is due to a lack of dissolved oxygen in the water. The low levels of oxygen are mainly due to a lack of aeration or poor water quality, which can then cause the fish to stress.

How do you stop a fish from dying?

How do you treat a sick fish at home?

Add antibiotics to the water and use antibiotic-medicated food. Maintain good water quality. Quarantine any fish with signs of the disease. Treat affected areas with topical disinfectants.

Can fish recover from lack of oxygen?

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.

How do you make fish oxygenated water?

More water movement always increases oxygenation. Add an additional filter or replace the existing filter with a higher capacity unit, if necessary. Other options are using a powerhead, putting a spray bar on the outlet of the filter, or using airstones.

How do you know if your fish is struggling to breathe?

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 simply moving around less. They will swim less vigorously and even eat less often.
