What's the difference between male and female angelfish?
The most accurate way to tell Male from Female is to watch them spawn.The female will lay the eggs while the male fertilizes them.
It does not have to be, but often is to preserve the fresh flavors of the fish while it is being transported long distances.
yes because that is why they dash if you step into a fish infested pond or something..
This question makes no sense- you need to clarify what you mean before it can be answered.
Will a Betta Fish eat another type of fish if it is hungry?
its kinda rare to see a beta eat a whole fish, usually they injure and bite other fishes. but its a high possibility that a beta could eat another fish if its really really hungry, due to its instincs, but usually the fish cant be bigger than the betta itself.
What compound is most toxic to freshwater fish?
Fish waste includes ammonia (NH3), which breaks down into nitrites, then nitrates. Both in your store and at customers' homes, freshwater fish aquariums should be closely monitored for levels of these three waste products.
Ammonia should test at zero in established tanks with sufficient nitrifying bacteria. However, ammonia can rise to very high concentrations in new tanks or when too many fish are added. Levels should be carefully monitored in new tanks and after adding fish, particularly in smaller tanks where waste can concentrate faster.
Nitrite (NO2) and nitrate (NO3) should be monitored closely. Ammonia is broken down into nitrite, which is less toxic but still dangerous to fish at high levels. Nitrite is then broken down into nitrate by another type of bacteria, completing the nitrogen cycle.
Nitrite generally is detected in only new tanks (during the initial phases of establishing nitrifying bacteria colonies) and when new fish are added. In established tanks, nitrite levels should test at zero as it breaks down into nitrate. Nitrate will accumulate in the aquarium over time but can be kept at safe levels by frequent partial water changes.
What is the difference between the kanduli fish and mud fish?
Kanduli fish grows in sea water and not slimy while the mudfish is slimy and has sharp whiskers that stings the one who holds it
Different types of small fish eat different types of food. Some smaller fish feed on dead fish while others feed on algae and plankton. There are a variety of foods a fish can eat.

On a fish what can be anal pectoral or pelvic?
A fish has several different types of fins. There are the pectoral fins, located beneath the operculum (gills). There is the pelvic fin, located at the bottom of the fish, below the pectoral fin. There is the anal fin, which i located behind the anus, and there is the dorsal fin as well. It is located on top of the fish.
What are the small hard pieces of skin that cover the body of a fish or reptile?
i for one am glad you asked that question, those hard pieces of skin are called scales, the scales are what cover the bodies of reptiles and fish, including whales and sharks, with fish they are mainly a water repellent used so that they can swim faster, on reptiles they are what obsorbes heat so that they can live, snakes though, unlike the majority of other reptiles shed the scales because the scales don't grown, nor do they stretch, so when the snake grows too large for the scales it finds a rock or branch to scrape its body against so that the scales will fall off, they even shed over their eyes and those whole on the sides of their heads what i believe are called "diapsids" pronounced "dye-ap-sids"
fish that feed frequently and can be hooked effortlessly.
Well, no. But as many other animals, they might be able to sense them.
Why fish put the small fish in their mouth?
To eat them.
However a small number of fish species have evolved a method of protecting their own young by "brooding" them in their mouths when danger threatens. This of cause means that the fry are more likely to survive to adulthood.
Why does a red fish look black in the ocean greater than water depth of 10 meters?
Has to do with reflected light, its wavelength, and how water effects it. Red light cannot travel as deep in water as green or blue. Therefor, when a red fish goes deeper the needed RED LIGHT cannot reach it and will not be reflected off the fish. SO! It looks black because it is REFLECTING no color. Thats what color is... reflected light.
