Fish Behavior

Fish feeding blocks are effective for feeding fish when you’re away. They offer convenience for vacations. Users notice that these blocks can slightly cloud the water and leave some sediment behind. Despite this, fish generally show contentment when using the blocks for a trial week or shorter periods. User reviews often highlight the convenience of … Read more

Fish feeder blocks work well for short-term feeding. They can provide food for 7-14 days, depending on tank size and conditions like water temperature (ideal above 72°F) and pH level (between 6.6 and 7.0). Monitor their usage to prevent overfeeding. For better results, consider using electronic feeders as an alternative. Some fish may have difficulty … Read more

Discus fish display unique parenting skills. They feed their young mucus from their bodies. This mucus acts like mammalian milk, offering vital nutrients and immune support as the fry develop. Fish parenting varies greatly, but few species care for their young as effectively as discus fish do. Certain fish, such as cichlids, exhibit mouthbrooding. They … Read more

Most fish do not feed their young directly. Fry usually search for food on their own. Some exceptions exist. Mouthbrooders, like Discus fish, offer nourishment through secretions. In contrast, some cichlid mothers may eat their own fry for survival. Commonly, breeders feed baby fish with brine shrimp as a key food source. However, some species … Read more

Fish do feed in the rain. Heavy rain increases run-off, bringing food sources like worms and insects into the river ecosystem. The flowing water stirs up small aquatic creatures. This creates a feeding frenzy, prompting fish to actively search for food. As a result, rainy days are often good for fishing success. When fishing on … Read more

Many fish, such as catfish, carp, and certain sharks, feed at night. Predatory fish hunt in low light, while nocturnal species use their strong sense of smell to locate food in the dark. Bottom-dwelling species also thrive at night. Night fishing is a great way to catch these fish effectively. For successful night fishing adventures, … Read more

Yes, fish commonly feed after rain. Rain alters barometric pressure and enhances water conditions, boosting oxygen levels. Runoff carries food sources, like worms, into the water, attracting fish. Surface-feeding species often search for food, especially after heavy rains. Fishing can be very productive during this time. The water quality also changes after rain. The oxygen … Read more

Fish eggs need fertilization to become embryos. Female fish release eggs into the water, where male fish fertilize them with sperm. This process is crucial for reproduction and occurs when fish reach sexual maturity. Fertilization commonly takes place in an aquatic environment during spawning. Several factors influence egg viability after fertilization. Water temperature plays a … Read more

Fish eat plastic, especially predatory species higher in the food chain. Research shows that a fish’s foraging strategy affects its likelihood of ingesting plastic. This behavior raises the risk of harmful effects, as these fish consume more plastic, impacting their health and the overall ecosystem. Research indicates that microplastics can accumulate in fish tissues, potentially … Read more

Yes, some fish eat coral. Corallivorous fishes, such as butterflyfishes and parrotfishes, feed on coral polyps. This activity may seem damaging, but it also plays an essential role in reef health. By eating dead or unhealthy coral, these fish promote new coral growth and help maintain ecological balance in coral reef ecosystems. Additionally, fish contribute … Read more
