Common Reasons Silver Arowana Refuses to Eat and How to Solve Them
A silver arowana refusing to eat is a fairly common occurrence in home aquariums, referring to a fish that previously fed normally suddenly refusing food, or a clear drop in how much it eats. This behavior is often not caused by a single factor; in most cases it is related to water quality, environment, food and the health of the fish.
The most common cause is water quality problems. Silver arowanas are relatively sensitive to water quality; rising ammonia nitrogen or nitrite in the water, or abrupt water changes that cause temperature fluctuations, can all reduce its appetite. In addition, a newly added fish is prone to stress-induced food refusal because the environment is unfamiliar, long-term feeding of a single type of food may cause anorexia, and overfeeding leading to indigestion can also stop it from eating.
When dealing with this, first test the water quality, change some of the water appropriately and keep the water temperature stable, then observe for a day or two to see whether the appetite recovers. If indigestion is suspected, you can stop feeding for a few days to let the digestive tract rest, and there is no need to force-feed during this period. Usually it is recommended to alternate animal-based foods such as small fish and shrimp with artificial feed, which both enriches the nutrition and reduces picky eating.
If the refusal to eat is accompanied by body surface injuries, rapid breathing, slow swimming or abnormal feces, then disease factors such as enteritis and parasites should be considered, and the fish should be isolated for observation and treated according to the symptoms in good time. In daily keeping, regular water changes, measured feeding and reducing disturbances will help most cases of food refusal gradually improve.
