What does a rainbow fish eat when it is in its own habitat and not in an aquarium?
Their natural diet comprises of quite a mixed bag namely insects, fresh water copepods or other crustaceans, insect larvae, worms, detritus, and smaller fish. Wild rainbow fish feed mainly on algae and other plants, but also eat aquatic insects, terrestrial insects, tadpoles, crustaceans and really small fish. A majority of their diet is however always made up by algae. When aquarists place rainbow fish in their aquariums, they often give them ordinary flake food with a low algae content. Even a really good high-quality flake food is however normally a bad choice for rainbow fish, because the composition of most "general" flake foods is tailored for omnivore fish that eat more meaty food and less algae food. A diet rich in
protein and low in fiber is not healthy for rainbow fish and will increase the risk of various health problems. Many people give their rainbow fish a protein rich, or even fatty, diet since this increases the growth rate. An increased growth rate is however not the same thing as a thriving fish. The fish may seem happy and healthy, but this type of diet will greatly increase the risk of future health problems .
If you can stand having some natural algae growing in your aquarium, this is naturally the best food source for your rainbow fish. Not only will the fish receive nutrients from the algae; they will also be able to carry out their natural foraging behavior. Algae or algae-based food should be ideally combined with vegetables. You can for instance give your rainbow fish boiled peas, pumpkin and zucchini. Staying away from all sorts of meaty food is however not a good idea. As mentioned above, wild rainbow fish feed on insects, crustaceans, small fish, etcetera. This means that they need a certain amount of meaty foods in the aquarium as well. The meaty food should however never make up more than 35-40% of the diet, and fatty food should be avoided altogether. You can for instance give your rainbow fish mosquito larvae, fruit flies and fish fillets. Stay away from food types that the rainbow fish could never obtain in the wild, such as beef heart.
They do it the same way we do, using intestinal peristalsis to move the fecal matter out through their anal sphincter. After that, it falls to the floor of their environment to be incorporated into the environment.

What types of fish eat Barnacles?
Some fish that eat barnacles include triggerfish, wrasses, and some species of gobies. These fish feed on barnacles by picking at their shells or scraping them off rocks. Barnacles are an important food source for many marine organisms.
How do fishes brethe under water?
Fish breathe underwater by extracting oxygen from the water through their gills. As water passes over the gills, oxygen is absorbed into the fish's bloodstream, while carbon dioxide is released back into the water. This process allows fish to extract the oxygen they need to survive in their aquatic environment.
Bream is a type of freshwater or saltwater fish belonging to the carp family. They have a flattened body and are popular among anglers for their fighting qualities. Bream are commonly found in lakes, rivers, and coastal waters around the world.
A freshwater fish is a type of fish that lives in freshwater habitats like lakes, rivers, and ponds. These fish have adapted to survive in the lower salinity levels of freshwater environments compared to saltwater fish. Examples of freshwater fish include trout, bass, and catfish.
What are the X-ray fishs predators?
Predators of X-ray fish include larger fish, birds, and mammals that prey on smaller fish in their habitat. These predators rely on their keen senses to detect and capture X-ray fish as a source of food.
What algae will consume depends on the particular species of algae, whether autotrophic, heterotrophic, or mixotrophic, and the conditions it is in. Photoautotrophic algae (plant-like algae) mostly need sunlight, Nitrogen, Potassium, and Phosphorus as well as water and CO2. Other species are able to survive without sunlight and others feed on bacteria and sugars instead of making their own sugars. Sometimes even photoautotrophic and heterotrophic algae if in lack of O2, they can no longer respirate so they go into anaerobic respiration and ferment.
Name the fish which emits light?
The fish which emits light is called a bioluminescent fish. Examples include anglerfish, lanternfish, and flashlight fish.
What fishes give birth to young alive?
Some examples of fishes that give birth to live young include guppies, mollies, swordtails, and platies. These fishes are known as livebearers and their offspring develop inside the mother's body before being born.
Fish move primarily by using their fins to propel themselves through the water. They use their tail fin to generate thrust and their pectoral and dorsal fins to steer and stabilize themselves. The shape and movement of the fins allow fish to swim in different directions at varying speeds.
How many ml in a mg of fish oil?

Do fish eyes function like a fish eye lens?
yes, but it's not what you think.
species with fixed eyes have super wide vision compare to a human, we see at about 54mm focal compared to a 35mm full frame camera. most fixed eyes fish see at 17-39mm equivalent.
species that have developed eyes movement generally do so because they lack the wider vision. it've been a while since i've seen the exact number, but i'm sure they still still pretty wide.
however, not all fish have "fish eye view" some species see narrow, some's eyes aren't even functional and in the process of disappearing through evolution.
last but not least, even though their eyes behave similarly, a camera could not represent their view, think of it as 2 fish lense camera pointing at 2 different direction with a blind spot in the front.
