Fish

Yes, a fish has weight in water due to the gravitational pull acting on its mass. However, the weight of the fish in water is offset by the buoyant force exerted by the water, which helps keep the fish afloat.

The jelly-like substance is likely fish eggs that the pregnant fish has released. These eggs are fertilized by the male fish and will hatch into baby fish if conditions are right. It is important to provide a safe environment for the eggs to develop if you want to raise the fry.

Most fish lay eggs in water, either attaching them to plants or structures or releasing them into the water. Some fish, like salmon and herring, migrate upstream to spawn in freshwater before returning to the ocean. There are a few exceptions, like the mudskipper, which is able to lay eggs on land.

The inside of a male fish typically contains organs such as the heart, liver, intestines, and swim bladder. Their reproductive organs will also be present, including testes for producing sperm. The specific appearance can vary depending on the species of fish.

Improperly prepared puffer fish can be deadly due to toxins within the fish.

Improperly handled and undercooked fish could be deadly due to microbiological growth.

Some people are deathly allergic to seafood.

But not all fish are deadly to all people.

It is not recommended to physically harm animals in any way. Fish are living beings that should be treated with respect and care. If you have a concern about a fish, the best course of action is to seek help from a professional who can provide guidance on how to address the issue in a humane manner.

Flying fish are not typically dangerous to humans. They use their ability to glide above the water as a way to escape from predators. If startled, they may end up in boats or hit people, but they do not pose a direct threat to humans.

Yeah, a rudimentary brain that controls basic functions of life.

I think they don't have a brain.

The world's smallest fish is Paedocypris progenetica from Indonesia. Mature females measure at 7.99 mm. This fish is a member of the carp family.

The life cycle of a pike fish begins with spawning in early spring. The female lays eggs in shallow water, which are fertilized by the male. The eggs hatch into larvae, which grow into juveniles and eventually mature into adult pike.

If the fish is more red than orange it could be a red wag swordtail or even a platy.

well... male- all orange with a line of black on the under side of the tale is a xiphophorus helleri swordtail from the southern mexico, Guatemala

Fry fish typically eat tiny aquatic organisms such as insect larvae, plankton, and small crustaceans. As they grow, they may also consume algae and plant matter. Providing a varied diet is important to ensure their growth and development.

Blobfish primarily eat small crustaceans, mollusks, and other small marine creatures that drift near the ocean floor. They are opportunistic feeders and will consume whatever food sources are available in their deep-sea habitat.

Common predators of pond fish include birds (such as herons and kingfishers), mammals (like raccoons and otters), and larger fish (such as bass or catfish). Consider adding protective measures like netting, floating plants, or providing hiding spots for your fish to help keep them safe from predators.

Angelfish should be fed 2-3 times a day, offering only what they can consume within 2-3 minutes to prevent overfeeding. It's important to provide a balanced diet that includes a mix of quality flake or pellet food, frozen foods, and live foods to meet their nutritional needs.

Meno fish are primarily herbivorous and feed on algae, plants, and small invertebrates found in their natural habitat. In a home aquarium, they can be fed a diet of high-quality vegetation-based flakes, pellets, and fresh vegetables like zucchini or spinach. It's important to provide a varied diet to ensure their nutritional needs are met.

Clownfish are generally not aggressive and do not pose a threat to humans or other fish species. However, they may become territorial and display aggressive behavior towards other fish if they feel their territory is being invaded or if they are protecting their eggs or young. It's important to ensure proper tank setup and space to minimize aggressive behaviors in clownfish.

Nova Scotia is home to a variety of fish species including Atlantic cod, haddock, mackerel, Atlantic salmon, lobster, and various shellfish like scallops and crabs. The province's diverse marine environment supports a rich variety of fish that are important for both commercial fishing and recreational angling.

Blind fish typically do not "see" in the traditional sense because they lack functional eyes or have significantly reduced eyesight. Instead, blind fish rely on other senses such as touch, smell, and a specialized lateral line system that detects vibrations and movement in the water to navigate their environment and locate prey.

Sardines belong to the herring family. The largest size a sardine can grow depends on which species of the herring family it belongs to. The largest size ranges from 26 centimeters to 40 centimeters.

The acidity for tropical fish? I think your referring to the acidity of the water in their aquarium...???

Generally, "tropical fish" do well with a neutral (7.0) or slightly acidic (6.7-6.9) PH level in the water of the tank. This is easy to test using a PH test kit from your pet store.

The acidity of the water is affected by whatever is IN the water with the fish---in the wild, the flora and fauna of the area dictates the PH (acid-neutral-alkaline) of the water. In general most of the common tropical fish (freshwater) sold in pet stores come originally from central/south America and Asia. The waters in these areas are slightly to mid level acidic depending on the time of year. These fish would be the common "community" tropical fish like tetras, gourami's, live bearers (guppies, mollies etc) and algae eaters/scavengers. The larger "cichlids" like Oscars, Jack Dempsy's etc are also from South America but are aggressive.

All do fine with an PH (acidity of 6.8-7.0) as most are commercially raised now anyway.

Don't put "wild" rocks in your tank as they could contain pollutants and be very calcium rich (like sea shells) and raise the PH to above 7.0 into the Alkaline level.

Some fish (like the African Cichlids) prefer a high alkaline environment...

Hope this helped,

Starfish move using tube feet located on the underside of their arms. These tube feet are filled with water, allowing the starfish to create suction and grip onto surfaces as they move. By contracting and expanding these tube feet in a coordinated manner, starfish can slowly crawl along the ocean floor.

No, flounder fish are not poisonous. They are safe to eat and are actually a popular choice in seafood dishes. Just make sure to cook them properly to avoid any foodborne illnesses.

Skate or ray fish have no bones. Only cartilage. I don't know about any freshwater ones one salt ocean.

Yes, flying fish are real. They have adapted to be able to glide above the water surface for considerable distances using their specially adapted fins. This behavior helps them evade predators and cover long distances.
