It depends on the size of the tank. Ideally most people get 5 gallon buckets of reef salt for ideal tanks.
A saltwater fish tank can be half freshwater and all of the saltwater fish will live but not for very long.
Damsels are indeed saltwater fish, they are related to both clown fish and chromis. However they are a much hardier fish and can slowly acclimated to be a freshwater fish.
The density and pressure of saltwater is different from freshwater as is much of the bacterias and parasites. The acidity of the water is also of concern as the lower the PH the higher the acidity of the water. Saltwater being of a higher PH would not handle the lower PH of freshwater very well. Also if moving a freshwater fish to saltwater that fish will lose a great amount of water in it's body causing death and if the saltwater fish is moved to freshwater it will gain great amounts of water causing death.
Freshwater aquariums have a different water chemistry, salinity level, and pH compared to saltwater environments. Saltwater fish are adapted to living in a specific salinity range and may struggle to regulate their ion balance in freshwater, leading to health issues or even death. Additionally, freshwater lacks essential minerals and elements that saltwater fish require for their health and wellbeing.
pretty much saltwater fish eat other fish in the wild. Out deep fish rely on bonita and other school fish for prey. If you are fishing, use dead or live baitfish such as bonita. This is used for bigger game fish. Inshore fishing can use a variety of bait including shrimp,live croakers, and small bait fish. There are a lot of choices in the ocean!

Certain fish, such as some kinds of sharks, have a special gland to process the salt changes in their bodies as needed. Piranha and fish without that gland living in a body of water with too much or too little salt would survive as well as an astronaut on the moon without a spacesuit.
Saltwater flyfishing is done with heavier tackle and typically uses wet flies resembling baitfish. However, saltwater fish can also be caught with "poppers," a surface lure similar to those used for freshwater bass fishing, though much larger. Saltwater species sought and caught with fly tackle include: bonefish, tuna, dorado (mahi-mahi), sailfish, tarpon, striped bass, salmon and marlin. Offshore saltwater species are usually attracted to the fly by "chumming" with small baitfish, or "teasing" the fish to the boat by trolling a large hookless lure. Many saltwater species, particularly large, fast and powerful fish, are not easily slowed down by "palming" the hand on the reel. Instead, a purpose-made saltwater reel for these species must have a powerful drag system.

Mackerels are saltwater fish. Tadpoles live in freshwater. Meaning a mackerel wouldn't have much chance of eating tadpoles.
The cost of caring for a pet fish can vary widely depending on the species, tank size, and equipment needed. On average, initial setup costs, including the aquarium, filter, heater, and decorations, can range from $100 to $500. Monthly expenses for food, water treatments, and maintenance typically add up to $10 to $30. Overall, the annual cost can range from a few hundred to over a thousand dollars, depending on the complexity of the setup and the type of fish.
Depends on the type of fish , anywhere from .22oz. to 1lb. unless your speeking about saltwater fish such as the tiger shark they give live birth and at birth young can weigh anywhere from six to ten pounds
