Fish Behavior

Fish from different species, like Dwarf Gourami and Neon Tetras, usually prefer to school with their own kind. They feel safest in larger groups of similar fish. While some may mix, their comfort and behavior improve in species-appropriate environments. Understanding fish preferences helps maintain harmony in the tank. In community tanks, schooling fish may interact … Read more

Fish-handler’s disease can cause hand eczema if cuts or scrapes get infected with Erysipelothrix rhusiopathiae. Symptoms include red, itchy skin and dermatitis. Fish allergies may also trigger eczema flare-ups, but the bacteria itself does not directly cause eczema. The bacteria typically responsible for this issue include species like Vibrio. These bacteria thrive in water and … Read more

Yes, you can apply fish emulsion to plants. Dilute ½ ounce (about 2 tablespoons) in 1 gallon of water. This covers 25 square feet. Apply every three weeks around 2cm from the plants. Fish emulsion improves soil health and supports plant growth at all stages. The strong scent fades quickly after application. However, there are … Read more

Fish have many sensory neurons in their fins. These neurons help fish detect touch and changes in their environment. Scientific studies show that fish possess a nervous system. However, fish perceive pain differently than humans. While they respond to injuries in their fins, their experience of pain does not match ours. Additionally, fins are richly … Read more

Yes, fish can feel pain, including in their fins. Scientific studies show that fish have pain receptors and sensory axons in their fins. These structures make their fins sensitive to harmful stimuli. While fish experience pain differently than humans, they can feel discomfort, fear, and stress. Moreover, research suggests that fish can experience emotional responses … Read more

Yes, some fish can feed in the dark. Nocturnal fish, like certain tetras and corydoras, use their smell and touch to find food. Most diurnal fish prefer feeding when it’s light, usually at dawn and dusk. It’s essential to know the fish types and manage waste by not overfeeding. Understanding night feeding is essential for … Read more

Fish farming can help reduce overfishing by easing the demand on wild fish species. By using controlled aquaculture, farmers manage fish populations and adopt sustainable practices. With proper regulations in place, fish farming can enhance seafood supply and support population recovery while minimizing environmental impact. Sustainable aquaculture practices minimize environmental impact. They focus on responsible … Read more

Fish absorb water through their gills via osmosis. Saltwater fish often drink water to replace what they lose, while freshwater fish take in water through their skin and gills without actively drinking. Both types use their gills for respiration, extracting oxygen from the water to support their body fluids and overall fish physiology. In freshwater … Read more

Fish eggs can die if they don’t get fertilized. Infertile eggs may develop fungus but are alive initially. Without a male fish, eggs won’t hatch. Successful fertilization happens when a male fish releases sperm to fertilize the eggs quickly, within two minutes. This process is crucial for fish like angelfish and parrot fish. Unfertilized eggs … Read more

Fish may die from not schooling due to increased stress and vulnerability. Schooling fish feel safer in groups. When alone, they can experience stress, become ill, and be less active. It’s essential to maintain a minimum group size in an aquarium to support their health, reduce stress, and promote proper group dynamics. Furthermore, fish are … Read more
