Do betta fish like other fish?

What are three adaptations of a cartilaginous fish?
The chondrichthyans are often thought of as primitive compared to bony fishes . Many chondrichthyans, however, have evolved sophisticated adaptations that have made them successful predators over a wide range of habitats.
sense of hearing
The senses of active predators, including many sharks, are especially well developed. A keen sense of hearing allows sharks to locate prey from as far away as 250 meters (800 feet). They are particularly sensitive to low-frequency vibrations such as those emitted by injured animals. Sound is detected through the ears and through the lateral line , a series of fluid-filled canals along the head and sides of the body that contain sensory cells sensitive to vibrations
sense of Sight
. As in many nocturnal mammals, the inside of a shark's eye is covered with a tapetum , a membrane that reflects light back into the eye, making it easier to see in dim light. Unlike most fishes, sharks can reduce and expand their pupils. In some species, the eyes are protected during feeding by the nictitating membrane, a structure similar to an eyelid.
sense of smell
The Elasmobranchi group has external nostrils on the lower side of the body; because of them, sharks can detect tiny concentrations of substances such as blood, which allows them to scent prey from distances of several hundred feet. Finally, sharks can detect electrical signals via the ampullae of Lorenzini, which are specialized organs distributed over a shark's head that detect changes in electrical currents. Sharks use these to sense the electrical fields emitted by the heart and muscles of their prey.
Tuna is not considered meat or poultry. It is actually a fish. You may be confused because stores do sell tuna sometimes as a tuna steak. It is also a pink color which may resemble beef. However, this color derives from the fishes' myoglobin. Tuna is indeed a fish.

How long can a fish stay in its bag that the workers put it in at the store?
As long as is necessary for the water temperatures to equalise. I would float the bag in the tank for at least an hour if the fish is not showing signs of distress. If it is distressed I would add some water to the bag every 5 minutes or so to speed things up a bit and then I would pour the bag water through a net into a bucket and place the fish from the net into the tank without adding the water from the bag to the tank.
What is a pregnant fish called?
There is no such thing as a pregnant goldfish. They are egg layers and so do not get pregnant. Gravid is the term used to describe an impregnated female livebearer and does not correctly refer to any species of egg laying fish. Gravid can not be used in reference to a goldfish. ** Gravidity, in essence, refers to "heavy with young" regardless if the organism is viviparous, oviparous, or ovoviviparous. According to Miriam-Webster online dictionary, this term is acceptable to define condition of any sexual reproductive product. It also specifically refers to "a gravid fish" as being full of eggs. Please refer to provided examples below. Granted, some sources define gravidity as "an implanted uterus" only, but the cited Example #2 below is inclusive of eggs as a means of development and delivery. http://www.merriam-webster.com/dictionary/gravidgravid Top of Form

then feed fish, providing large regions of successful coastal fisheries.

How fish communicate with other fishes?
Senses play an important part in fish communication. Visual communication is important to most fish. Body movements, postures, colors and color patterns are the primary means of visual communication. Sound is also used for communication. Sounds are produced by grinding teeth, flexing or contracting muscles and vibrating the swim bladder. Fish also communicate by releasing chemicals called PHEROMONES. These are chemical signals produced by an animal that, when released, influence the behavior of others of the same species. The sense of smell is important for this form of communication. But fish do not have a language so Finding Nemo can be misleading.

Why do fish bleed when caught?
apparently if a fish is bleeding from the gills it means there is not enough oxygen. Or because a previous fish had died in the same water and you havent changed it. The bacteria can spread throughout the water while the fish is swimming causing it to get infected. You might have a very dirty tank. that is also important to clean HALF of it if it very dirrty. But usually i would clean my tank every 2 weeks MAX and make sure only to get around 25 percent out.

They might eat the fry, but most fish will eat the fry. My dwarf puffer lives with a school of tetras and has never caused them any problems.
