CATDOLL : CATDOLL: What colors do predatory fish prefer?

1. What colors do predatory fish prefer?

There is no clear answer. Different fish prefer different colors. There is a very interesting experiment in which fish are fed with different colored feeds, but each fish is not dyed with the same color. This shows that different fish have different preferences for colors. Fish are more sensitive to water color and green. Fish and humans also have different perceptions of color. People are more sensitive to red and yellow, while fish are more sensitive to water color and green. This is because water absorbs most of the light and only allows the color of the water to pass through. Therefore, fish are more sensitive to water color and green.

2. What taste do carnivorous fish like?

Carnivorous fish like fishy smells. Carnivorous fish are fish in the ocean or freshwater that mainly feed on animals. According to the objects they feed on, they can be divided into two categories: one is mild carnivorous fish, also known as "primary carnivorous fish", which mainly feed on aquatic invertebrates, and can be divided into planktonic fish and benthic fish. The former includes bighead carp, herring, shad, anchovy, basking shark, whale shark, etc., and the latter includes black carp, mullet, sea bream and flounder, etc.

The other type is ferocious carnivorous fish, also known as "secondary carnivorous fish" or "piscivorous fish", which mainly feed on vertebrates (especially fish), such as pike, bighead carp, snakehead, hairtail, and man-eating shark.

3. What does the Egyptian angelfish eat? Is it an omnivorous fish?

What does the Egyptian angelfish eat? The Egyptian angelfish is an ornamental fish that is relatively easy to raise. It is an omnivorous ornamental fish. It does not have very high requirements for food and can accept general artificial baits. The Egyptian angelfish especially likes to eat live bait and raw bait, but in order to make the food more nutritious, you should pay attention to the reasonable combination of baits.

The Egyptian Angelfish lives in the Amazon River, where it has a rich diet of mosquito larvae, earthworms, water fleas, aquatic insects, small fish, shrimps, and other things. It is an omnivorous fish. Therefore, if you want to keep it in an aquarium, I will list several baits that are easier to get.

1. Frozen bloodworms: Almost all fish like to eat this food, but because the source is not very clean, most of them are bacteria-carrying, and fish are prone to get sick if fed for a long time. It is recommended that healthy fish should not be fed this food. However, for fish with no appetite, it can be a good bait. It is better to feed it for a while, and then change to other baits when the fish are stable.

2. Frozen brine shrimp: Brine shrimp is a crustacean that lives in seawater. It is not like water fleas, but more like shrimp. Because it grows in brackish water, some freshwater bacteria will not be brought in [because seawater bacteria cannot survive in freshwater, so there is no problem of bacteria]. It is rich in calcium, which is the best bait for Egyptian angelfish that value height. However, you should pay attention to whether the brine shrimp you bought is fresh [open it and smell it to see if it smells bad. If it smells bad, it is not fresh, so try to use less]. It is a good choice to use brine shrimp as a staple food!

3. Fish hamburgers: Usually used as a great feed for angelfish, because its ingredients are very nutritious for fish and can make the fish thicker and fatter. It is also a very good feed for Egyptian angelfish, but hamburgers can easily pollute the water quality, so feed in small amounts and eat them up immediately without leaving any leftovers. [At first, they may not be used to it, so you can stop feeding for a day and then feed again. Feed a little at first and see how it goes. Slowly they will get used to it.

In addition to the above baits, you can also feed with artificial feed [add a timer feeder, thin flakes are more suitable, but don't let your beloved fish eat too much or it will be very picky. Don't feed too much at one time, it will pollute the water quality. I don't recommend feeding here, just treat it as adding or subtracting food when you are at work. After all, the Egyptian Angelfish is so precious, if you want to keep it strong, you must rely on your careful care!

4. Is the pitcher plant a carnivorous plant?

The pitcher plant is one of the representatives of carnivorous plants. It is a carnivorous plant similar to the pitcher plant. It passively captures insects with a sac, which is also a predator. Under strong sunlight, the sac will appear purple to attract insects. When the insect slides into the sac, the glands in the sac will secrete special juice to surround and suffocate the insect, which will eventually be decomposed by digestive juice to provide the nutrients needed for the growth of the pitcher plant.

So how did plants like the pitcher plant become carnivorous? It has both carnivorous leaves (which contain fluids that can digest animals) and non-carnivorous leaves.

By biologically comparing the digestive juices in the leaves of the carnivorous pitcher plant with those of its three distant relatives - Drosera athyllis, Nepenthes philippinarum and Pitcher plant - the researchers found that genes involved in stress response in other plants have undergone functional changes in these four carnivorous plants, and their functions are equivalent to digestive juice proteins.

6. What plants did herbivorous dinosaurs mainly eat?

Abstract: Herbivorous dinosaurs in different periods ate different foods.

During the Triassic period, the plants that herbivorous dinosaurs could eat mainly included conifers, ginkgo trees, cycads, and smaller ferns, horsetails, and lycopods. During the Jurassic period, herbivorous dinosaurs mainly ate the leaves of conifers. In the middle to late Cretaceous period, many flowering plants and shrubs appeared on the earth, such as magnolias and walnuts, and some plant-eating dinosaurs chose to feed on them.

Wild fish in small rivers in the south mainly eat aquatic animals, such as small fish, shrimps and insects. Usually the small fish in the river are white minnow, crucian carp, minnow, grass carp, silver carp, carp, roundhead bream, etc. They have strong adaptability and are not very demanding on temperature.

Their diet is often very diverse, and they can eat a lot of food, which makes it convenient for them to forage in different water systems. Some of them have weak reproductive capacity, so they also have the habit of protecting young fish.

8. What kind of grass does the Chinese soft-shelled turtle like to eat?

Chinese soft-shelled turtles are omnivorous animals, and they prefer to eat most aquatic plants. In the wild, they will eat centipede grass, pennywort, small duckweed, large duckweed, water money, water hyacinth and other aquatic plants. Especially after adulthood, soft-shelled turtles like to nibble on aquatic plants. When breeding soft-shelled turtles artificially, it is best not to plant aquatic plants. Because soft-shelled turtles have the habit of chewing on plant roots and stems, if breeders plant aquatic plants, they may be eaten by soft-shelled turtles.

However, it can only be used as a supplementary food and eaten occasionally, and the staple food should still be cat food.
