Why Can’t My Betta Fish Swim? Top Causes, Symptoms, and Effective Treatments

Betta fish may struggle to swim because of swim bladder disease, which affects buoyancy. Common causes are overfeeding, internal growths, gastrointestinal problems, and injury. Environmental factors, like poor water quality or low temperatures, can also contribute. Proper care and water maintenance are essential for recovery. Injuries are also a concern, as physical damage can impact … Read more

Why Can’t My Betta Fish Stay Afloat? Causes, Symptoms, and Treatment Solutions

Betta fish might have trouble staying afloat due to swim bladder disease. This condition can lead to buoyancy issues. Common causes include overfeeding and gastrointestinal problems. Symptoms are floating sideways or sinking. You can help by giving them an Epsom salt bath and fasting to improve their condition. To treat these conditions, first, check the … Read more

Why Can’t My Betta Fish Swim? Causes, Symptoms, and Treatments for Swim Bladder Issues

Betta fish can have trouble swimming because of swim bladder disease. This condition affects their buoyancy. Common causes include overfeeding, injuries, parasites, and nutrition problems. You may notice abnormal swimming behavior. Treatment can be simple, but keeping the right feeding habits and tank conditions helps them recover better. Several causes contribute to swim bladder issues … Read more

Why Can’t Marine Fish Produce PUFA? Exploring Their Unique Fatty Acid Requirements

Marine fish cannot produce long-chain polyunsaturated fatty acids (LC-PUFA) like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) because they lack the necessary enzymatic activities for biosynthesis. Instead, they rely on dietary sources, such as microalgae, to obtain these essential fatty acids. This reliance on diet is a key factor in understanding marine fish nutrition. Marine … Read more

Marine Fish: Why Can’t They Produce PUFA and What It Means for Their Fatty Acid Needs

Marine fish cannot produce long-chain polyunsaturated fatty acids (LC-PUFA) like EPA, DHA, and ARA from C18 precursors. They lack sufficient enzymatic activity for this biosynthesis. As a result, marine fish depend on their diet, mainly microalgae and other sources, to meet their essential PUFA needs. The inability to synthesize PUFAs compels marine fish to consume … Read more

Freshwater Fish and Osmoregulation: Why Can’t They Be Isosmotic?

Freshwater fish cannot be isosmotic in saltwater because their internal salinity is lower than the external saltwater. This difference in tonicity causes water to move out of their cells through osmosis, leading to dehydration and potential death. Unlike saltwater fish, freshwater fish struggle to manage their salt levels in hypertonic environments. To combat this, freshwater … Read more

Why Can’t 99% of Fish Move Between Sea and Freshwater? Survival Mechanisms Explained

Saltwater fish cannot survive in freshwater because of osmoregulation challenges. Their bodies have a higher salt concentration than freshwater. This difference causes salt loss in freshwater and makes it hard for them to adapt. Fish have specialized adaptations like gill function to thrive in their environments, restricting their movement between sea and freshwater. These physiological … Read more
