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

Symptoms: You should observe your fish often for any of these signs of stress.

1. Gasping at the Surface: If a fish is gasping his mouth at the surface, this is a sign of stress brought on by poor water conditions, usually a lack of oxygen.
2. Appetite: If a fish is stressed, oftentimes he will not eat.

Why does my fish keep opening its mouth?

The primary cause of a tropical fish appearing to breath a lot is down to there not being enough oxygen in the water, they therefore have to use their mouths to suck in oxygen rather than take it in through their gills.

How do I give my fish more oxygen?

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.

How do you know if your fish is suffering?

Sick fish

• Loss of appetite.
• 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.

How do I stop my fish from gasping?

If your fish are gasping for air you should quickly oxygenate the water by turning on a hose or any other water pump and spraying the water in the air so it gets oxygenated and then lands in the water garden. Doing a partial water change is also recommended.

Why do my fish stay in one corner of the tank?

Heat. While most quality aquarium heaters are good at disbursing heat in such a way that the water stays at a constant temperature, you may find fish hanging out on one side of the tank rather than another because they prefer the temperature.
