We’ve already established that fish get sick, so how can you recognize when something is wrong? Signs of illness can be broken down into two categories: physical and behavioral.
These indicators of illness can be very easy to spot. Physical signs of disease include:
- Changes in coloration
- Asymmetrical body shape
- Misshapen fins
- Etc, etc etc
Most of the times, these changes are fairly obvious, but especially in the case of coelomic tumors, subtle changes can be very hard to spot. Here are some examples of physical signs of disease:
Behavioral signs of disease are harder to spot. If you don’t check your fish out every day, these signs can be very difficult to spot. A 5-minute fish viewing session twice a day is recommended at bare minimum. Behavioral signs of disease include:
- Incorrect body position
- Negative/positive buoyancy
- Avoiding areas of tank/pond
- Hiding/unsocial (species-specific)
- Swimming behavior
- Non-seasonal change in appetite/feeding behavior
In order to recognize “normal” behavior, you may need to look outside your home pond/tank. What may be “normal” in your pond may be very obviously not normal if you watch other fish of the same species in a different environment. Call up the neighbors and arrange a pond/tank social hour at a different home each week/month!
If you have a behavior that you cannot identify as normal or abnormal, CALL A PROFESSIONAL. Our office number is (831) 278-1081. It is better to be certain than let a unknown behavior slide for too long.
