Freshwater fish lose water through their gills due to osmosis. The water around them has lower salt concentration than their body fluids. To prevent excessive water loss, they actively take in salt ions and excrete dilute urine. This process helps them maintain osmotic balance and homeostasis in their aquatic environment. Osmoregulation involves several physiological processes. … Read more

Freshwater fish do not lose salts to their environment. They retain salts and produce large amounts of dilute urine. Their specialized kidneys help manage osmotic balance by filtering out excess water. In contrast, marine fish lose salts. They excrete excess salt to conserve water and produce concentrated urine. Osmoregulation involves a series of physiological adjustments … Read more

Freshwater fish get rid of salt in their urine. Their kidneys help maintain osmotic balance. These fish absorb excess water from their surroundings, producing large amounts of dilute urine. This way, they eliminate extra water while minimizing salt loss, ensuring a stable internal salt concentration. To expel excess water, freshwater fish produce large volumes of … Read more

Cherry shrimp eat only dead or decaying fish eggs. Amano shrimp serve as cleaners, removing fungus and infertile eggs without harming healthy ones. They do not consume live fish eggs or fry. While shrimp may nibble on eggs if they are hungry, their main role is to help keep the egg area clean. Cherry shrimp, … Read more

In saltwater ecosystems, plankton is a key food source for young fish such as menhaden and herrings. Crustaceans like crabs, lobsters, and shrimp also eat plankton. Larger carnivorous fish, including tuna, halibut, sharks, and squid, then feed on these smaller plankton-eating organisms. Another excellent choice is the Neon Goby, known for its cleaning behavior and … Read more
