Fish Behavior

Plastic plants can tear fish fins if they are not aquarium-safe. Harmful chemicals may be released. Fish with fragile fins, such as bettas and bubble-eye goldfish, are especially at risk from sharp edges. Always select soft, aquarium-safe plants to protect your fish and ensure their health and safety. To ensure the health of your betta, … Read more

Most fish species fertilize their eggs externally. The female lays the eggs in the water, while the male releases sperm onto them. This process is known as spawning. The eggs do not have a protective shell and require a water environment to survive. If the eggs dry out, they will die. The fascinating reproduction process … Read more

The folktale “Why the Fish Has Scales” tells how a king crab cursed a beautiful maiden, giving fish their protective scales. These scales represent lost beauty and safety. The story explores themes of loss and adaptation, reflecting cultural values and the power of nature. The intricate designs and shimmering appearance of fish scales often highlight … Read more

Shorter fins in betta fish may stem from fin rot, water quality issues, or stress. Check for ammonia poisoning in your tank. Ensure water temperature is above 78°F and provide proper feeding. Maintaining good tank conditions supports the healing process and can help fins grow back over time. Symptoms of fin loss vary. You may … Read more

Fish have fins for locomotion, balance, stability, and steering. They have different types of fins: dorsal, adipose, caudal, anal, pelvic, and pectoral. Fins help fish move smoothly in water. They allow fish to change direction and maintain control, which aids their survival in various aquatic environments. There are various types of fins, including pectoral, pelvic, … Read more

When water temperature increases, fish metabolism speeds up. This faster metabolic function raises the need for dissolved oxygen (DO). As a result, fish respiration rate also increases to fulfill their oxygen requirements. Higher temperatures can also affect their feeding and digestive habits, boosting their overall activity. This increase in the respiration rate allows fish to … Read more

Humans and fish have similar internal organs because of shared evolutionary history. Both species possess organs such as hearts, livers, and kidneys. Fish excrete ammonia through gills, while humans convert waste to urea. These similarities emphasize our connection to ancient aquatic ancestors and showcase the evolution of organ functions. In fish, gills function to extract … Read more

Fish jump out of water mainly for two scientific reasons. During spawning, salmon and steelhead leap to loosen eggs. They also jump to shake off parasites like sea-lice. Furthermore, this behavior can help avoid predators. Additionally, jumping can enhance social interactions within schools of fish. Synchronization is also an important aspect of this behavior. Fish … Read more

Advanced fish have symmetrical tail fins, called homocercal fins. These fins improve maneuverability and thrust. This design offers teleost fishes an evolutionary edge over non-teleost species. The streamlined shape allows for faster turns and efficient swimming, which aids in their survival and overall evolutionary success. Furthermore, symmetrical tail fins improve propulsion efficiency. Fish can generate … Read more

Fish school together for survival. This teamwork helps them evade predators by looking like a larger group. It also aids in finding food and spotting mates. By swimming in a school, fish save energy, allowing them to glide smoothly through the water and increase their chances of survival. Another reason fish school together is for … Read more
