4. Red or White Sores
Many things can cause sores on fish such as fights with other fish, scraping on sharp rocks, and small wounds that get infected and grow bigger.
A new small sore can usually be cured. Older or larger sores are more difficult to treat, but sometimes you can succeed, and treating your fish will make it less likely that other fish will be infected by the fish with the sore.

5. Gasping at the Surface
A fish that is gasping at the surface of the water is usually suffering from a lack of oxygen, that could be due to a lack of oxygen in the water or the fish's inability to absorb the oxygen from the water.
If there is just one or only a few fish gasping at the surface, but the other fish are normal, then the water probably has plenty of oxygen and you should immediately treat the gasping fish.
On the other hand, if almost all the fish are gasping, then there is probably a lack of oxygen in the water, and you should immediately do all of the following:
|
|
Check the Filter to be sure it's working properly. If it's not working properly, immediately fix it. Click here for more information about Aquarium Filters. |
|
Check the Temperature of the water on the thermometer, if this aquarium has a heater. If the temperature is out of the correct range, then adjust the aquarium heater. Click here for more about heaters, thermometers, and adjusting the temperature. |
|
Check the water surface, if there's oil or scum then carefully scoop water off the surface until you've removed two inches of water. Replace the water with fresh safe water. Click here for more about safe water. |
|
Add Aquarium Salt until the water has a total of 1 Tablespoon of aquarium salt for each 5 gallons of water. Click here for more about Aquarium Salt. |
|
Add Water Conditioner, which is available in stores that sell pet fish. The correct dose is on the bottle. Click here for more information about water Conditioner. |

6. Crashed on the Bottom
When fish crash on the bottom and do not swim, it is usually a sign that they are exhausted. There are many reasons a fish can become exhausted, but quite often they have been sick, and probably showed symptoms such as gasping, shimmy, or clamped fins, before they became tired and crashed on the bottom.
So the Recommended Treatment was not started promptly, and chances of curing a fish that is crashed on the bottom are less, but the Recommended Treatment may work and will probably protect the other fish that came in contact with the crashed fish. Click here for more about a Recommended Treatment.

7. Glancing
is a fish behavior where a fish rubs itself on the bottom of the aquarium, or on the gravel, or on a rock or ornament. The fish rubs or glances because it's itchy.
An itchy fish often develops more serious Signs of Stress and Disease. If you see your fish glancing, you should immediately treat your aquarium. Click here for more about a Recommended Treatment. |

8. Loss of Appetite
If your fish is not eating or takes food in its mouth and then immediately spits it out, your fish is showing one of the Signs of Stress and Disease.

9. Other Signs of Stress
There are many other Signs of Stress and Disease in fish. For example, there is so-called "fin rot" where the edges of the fish's fins disintegrate, or "pop eye" where the fish's eye bulges out, or "cotton mouth" where the fish has patches that look like cotton around it's mouth, but most of these more pronounced Signs of Stress and Disease occur after the more subtle Signs of Stress and Disease that are listed above.
"Fin rot", "pop eye", "dropsy", and "cotton mouth" are difficult to cure. But before they occur, the fish often show milder Signs of Stress and Disease like clamped fins. If you treat a fish at the first Sign of Stress and Disease, you'll have a much better chance of curing it. |

Take Immediate Action
If you see any of the symptoms listed above or if several fish have recently died in your aquarium, you should immediately take action and treat your fish.
When fish can be cured, the Recommended Treatment is usually the same for all of the symptoms listed above.
