Are angelfish herbivores carnivores or omnivores?

User Avatar

Asked by Wiki User

They are omnivores. I have seen them eat live brine shrimp and herbivore flake food.

There are 86 different species of Marine Angelfish and 3 species of Freshwater Angelfish.

While most Angelfish species are omnivorous; some Angelfish species are completely herbivorous (algae eaters), and some are completely carnivorous (zooplankton eaters).

Most angelfish are omnivores.

yes

How many chromosomes are present in goldfish?

User Avatar

Asked by Wiki User

yes there are because in a goldfish body cell there are 94 chromosomes. in order to find the amount of chromosomes in a sex cell of a goldfish you need to divide the body cells by two. this is so because in order to make another goldfish half need to come from daddy and half need to come from mommy this is why you divide by half. therefore there are 47 chromosomes in a goldfish's sex cell.

Mutualism in the ocean?

User Avatar

Asked by Wiki User

Mutualism in the ocean involves interactions between different species that benefit both parties. For example, cleaner fish remove parasites from other fish, benefiting both by one gaining food and the other being cleaned. Coral reefs are another example where coral and algae have a mutualistic relationship where both benefit from the exchange of nutrients and shelter.

Does a cone-shaped water tank increase psi coming out of tap?

User Avatar

Asked by Wiki User

No, a cone-shaped water tank will not increase the psi (pressure) coming out of a tap. The pressure at the tap is determined by the water pressure in the plumbing system and is not affected by the shape of the water tank.

How big do comet goldfish get?

User Avatar

Asked by Wiki User

Comet goldfish typically grow to be around 12 inches long, but some can reach up to 14 inches in length if provided with the proper care and environment. They are among the larger goldfish varieties and require a spacious tank to thrive and reach their full size.

What does algae need to grow?

User Avatar

Asked by Wiki User

Algae primarily need light, water, and nutrients (like nitrogen and phosphorus) to grow. They also require a suitable temperature and pH level in their environment for optimal growth.

Does WD-40 contain fish oil?

User Avatar

Asked by Schnazola

Main ingredients, from the material safety data sheet, are: * 50%: Stoddard solvent (mineral spirits, somewhat similar to, but not the same as, kerosene) * 25%: Liquefied petroleum gas (presumably as a propellant, carbon dioxide is used now to reduce considerable flammability) * 15+%: Mineral oil (light lubricating oil) * 10-%: Inert ingredients No Fish oil in WD-40...

Can ozone be used to remove H2S from drinking water?

User Avatar

Asked by Wiki User

Yes, ozone can be used to remove H2S from drinking water by oxidizing it into sulfur and other byproducts. The reaction typically involves converting H2S to elemental sulfur, which can then be removed through filtration or settling processes. Ozone is an effective oxidizing agent for treating water contaminated with H2S.

Why has your aftershave turned cloudy?

User Avatar

Asked by Wiki User

Aftershave can turn cloudy due to a variety of reasons such as temperature fluctuations, exposure to air, or the ingredients separating over time. It may not affect the product's effectiveness, but if you're concerned, it's best to discard it and purchase a new one.

Is a goldfish a herbivore?

User Avatar

Asked by Wiki User

Goldfish are omnivores, meaning they eat both plant-based and animal-based foods. While they do consume plants and algae as part of their diet, they also need protein from sources such as insects, worms, and small crustaceans.

How fast does a comet go?

User Avatar

Asked by Wiki User

Comets can travel at speeds of up to 150,000 miles per hour (240,000 kilometers per hour) as they move through space. However, their speed can vary depending on their distance from the Sun and the gravitational forces acting upon them.

Why do bugs turn upside down when they die?

User Avatar

Asked by Wiki User

Creatures with exoskeletons frequently have a primitive muscle/blood flow circulation system tied into each other and it is hydraulic by nature. The natural state of their legs is curled up and a force of exertion combined with the pushing of blood through their legs causes them to straighten. They have fine motor control of this which allows them to move, in fact it's probably unconscious such as the way we move our limbs, the process is lsot on us we just know we can do it.

Now, when the insect in question hasn't got enough food or water they grow weak, or with something like old age. So they find it harder to exert to force their legs "open" So imagine their standing on all their legs and can't summon the effort to keep the set on one side open. That side will collapse and they will tip. This causes them to roll over onto their backs. You can try this with a healthy insect and they will tilt and get back up but it's a strain and they use their legs a lot. When they are too weak to do this they are stuck, and frequently die shortly afterwards as they become too weak to right themselves.

What are some examples of biological filtration in a reef tank?

User Avatar

Asked by Naveedassiraj

Some examples of biological filtration in a reef tank include nitrifying bacteria breaking down ammonia into nitrites and then into nitrates, macroalgae absorbing nutrients like nitrates and phosphates, and live rock providing surface area for beneficial bacteria to colonize and process organic waste.

Setting up a fresh water aquarium?

User Avatar

Asked by Wiki User

To set up a freshwater aquarium, you will need an aquarium tank, filter, heater, substrate, decorations, water conditioner, and fish food. Rinse the tank and substrates before setting up, add water, install the filter and heater, then let the tank cycle for a few weeks before introducing fish. Be sure to monitor water parameters like pH, ammonia, and nitrite levels regularly to ensure a healthy environment for your fish.

Dangers in entering a chemical tank for maintenance operation?

User Avatar

Asked by Wiki User

Entering a chemical tank presents numerous dangers, such as exposure to toxic fumes, suffocation from lack of oxygen or presence of other gases, and risks of fire or explosions due to chemical reactions. It is also possible to be overcome by the chemicals or become trapped inside the tank, leading to serious injury or death. Proper safety protocols, training, and equipment are essential to mitigate these risks.

If your neon srt-4 has a misfire what should you do?

User Avatar

Asked by Wiki User

If your Neon SRT-4 is experiencing a misfire, it is recommended to first check the spark plugs and ignition coils for any signs of damage or wear. Next, inspect the fuel injectors and fuel system for any issues. It's also a good idea to scan the car's computer for any error codes that may point to the source of the misfire.

What factors make water soft?

User Avatar

Asked by Wiki User

Water is considered soft when it contains low levels of calcium and magnesium ions. These ions are responsible for the hardness of water by forming scale buildup. Water softeners can remove these ions through ion exchange or other methods to make water soft.

How do black light uv kills algae?

User Avatar

Asked by Wiki User

Black light UV works by emitting ultraviolet (UV) radiation that damages the DNA of algae, preventing the algae from reproducing and eventually killing them. The UV light targets the cells of the algae, disrupting their biological processes and ultimately leading to their death.

Will a tank full of water and a tank filled with water and fish swimming weigh the same on a scale?

User Avatar

Asked by Wiki User

That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more.

This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?

How do you lower alkalinity in salt water aquarium?

User Avatar

Asked by Wiki User

To lower alkalinity in a saltwater aquarium, you can perform partial water changes using reverse osmosis water, avoid using products containing carbonate or bicarbonate, and use a protein skimmer to reduce organic waste buildup. Monitoring alkalinity levels regularly will help you adjust and maintain them within the desired range for your aquarium.
