To keep the fins healthy, maintain clean water. This helps prevent problems like fin rot and supports good aquarium care. Proper care for betta … Read more

Acellular fish skin, especially from North Atlantic cod, is suitable for human tissue transplants. Kerecis fish skin grafts promote wound healing. They contain high levels of collagen, have low immunogenicity, and possess anti-inflammatory properties. FDA-approved, this fish skin offers a promising option for skin repair. Furthermore, fish skin has antimicrobial properties. These help to prevent … Read more

The ideal ammonia (NH₃) to ammonium (NH₄⁺) ratio for a betta fish tank keeps NH₃ below 0.25 ppm. At a pH of 7, most nitrogen is in the form of NH₄⁺, with less than 2% as NH₃. Regular testing with an API test kit helps ensure safe levels and supports a healthy environment for your … Read more

Fish use their lateral line system to detect changes in water pressure. This system has mechanosensory organs along the fish’s head and body. These organs sense variations in vibrations and pressure. This ability helps fish navigate their environment and respond to changes around them effectively. When water shifts due to the movement of other organisms … Read more

Lampreys reproduce by laying eggs in riverbed sediment. Adult lampreys vary in size from 5 to 40 inches long. Lampreys have a parasitic lifestyle, attaching to other fish and … Read more

Common factors affecting pH levels in fish tanks include overfeeding, decaying organic matter, and high levels of calcium carbonate and alkaline salts like sodium bicarbonate. Excessive use of alkaline substances such as baking soda, limestone, and coral sand can also lead to pH fluctuations, impacting fish health. Symptoms of abnormal pH levels include fish stress, … Read more

Marine fishes share adaptations like gills for oxygen extraction and streamlined bodies for efficient swimming. They control buoyancy for movement. Other adaptations include camouflage for escaping predators, osmoregulation for maintaining salt balance, and diverse reproductive strategies to survive in ocean environments. Physiologically, marine fishes maintain osmotic balance through specialized cells in their gills. These cells … Read more

Marine fishes have important adaptations. They have streamlined bodies for efficient swimming. Gills extract oxygen from water. They use swim bladders to control buoyancy. Bright colors and patterns help with camouflage and attract mates, improving their chances of survival in various marine environments. Different ecosystems encompass unique habitats, including coral reefs, open ocean, and deep-sea … Read more
