Care of Fish

No. Generally smells are caused by wet substances evaporating. Activated charcoal will absorb the moisture and reduce and eliminate the smell. Baking powder, baking soda, salt, and other substances that readily absorb moisture will accomplish the same.

It is difficult to estimate the exact number of sea urchins in the world due to various species and different habitats they occupy. However, sea urchin populations can vary greatly depending on factors such as environmental conditions and food availability.

Yes, koi are omnivorous and may eat small fish like minnows if given the opportunity. However, in a well-fed koi pond with ample food, they are less likely to hunt for minnows. It is always best to provide a balanced diet for koi to prevent them from preying on other fish in the pond.

Milkfish got its name because of its milky white coloration and its reputation for having a rich and creamy taste. The name "milkfish" is a direct translation from its Filipino name, "bangus," which is also derived from the same visual and taste characteristics.

Hard water has natural ions dissolved in it. It keeps shampoo for forming suds, it forms soap scum, and it leaves calcium and other deposits in your plumbing. Soft water doesn't have these ions.

If you step on a sea urchin, immediately soak the affected area in hot water (not scalding) for 30-90 minutes to help ease the pain. Seek medical attention if spines remain embedded or if you experience signs of infection, such as redness, swelling, or pus.

Tap water is public water that you get out of the tap of your kitchen sink. This term is used to distinguish from purified bottled water. tap water is water you get from the tap. In other words, it's not bottled.

Sea urchins reproduce sexually, with separate male and female individuals releasing eggs and sperm into the water for fertilization to occur externally. They can also reproduce asexually through a process called fragmentation, where a piece of the sea urchin's body can regenerate into a new individual.

Sea urchins are purple, red, orange, yellow/orange, and a mix of red and purple.(Sea Urchins come in many shapes sizes and colors.)

It will take 9 days to empty a 65-gallon tank by removing 7 gallons a day (65 gallons ÷ 7 gallons/day = approximately 9 days).

because it has either been threatened or frightened

Color change is normal in goldfish they often will change colors multiple times in their life. However, if the black is streaky and brownish, or if the color change is mainly at the lips and edges of the fins, that means the ammonia in the tank has reached a dangerous level and is actually burning your fish. Just to be on the safe side, test the ammonia level in you tank.

To pick up a crawdad without getting pinched, approach it from behind and grasp it firmly but gently around the body between the claws. Avoid grabbing the claws or the tail to prevent being pinched. Holding them securely and steadily will usually prevent them from pinching you.

To calculate the volume of water in the fish tank, you multiply the length, width, and depth: 122 cm x 46 cm x 36 cm = 201,312 cubic cm. 1 cubic cm is equal to 0.000264172 gallons, so 201,312 cubic cm equals approximately 53.08 gallons of water in the fish tank.

No, many aquarists choose the go 'bare bottom', with no substrate at the bottom of the tank. It is used most often in aquariums keeping the more delecate small polyp stony corals(SPS), as it helps to keep nutrients at a minimum.

There are many orders of sea urchins. The ones in the Subclass Euechinoidea go like this: Superorder Atelostomata - Orders Cassiduloida and Spatangoida; Superorder Diadematacea - Orders Diadematoida, Echinothurioida, and Pedinoida; Superorder Echinacea - Orders Arbacioida, Echinoida, Phymosomatoida, Salenioida, and Temnopleurioda; Superorder Gnathostomata - Orders Clypeasterioda (sand dollars) and Holectypoida.

The pea crab is a scavenger, a food source and an indicator of the health of the ocean. As the scavenger, eating what washes on shore, they have been known to imposex, change genitalia, based on the pollutants found in the ocean. They are also an important food source for fish, birds and other crabs.

No mammals are fish. Mammals and fish are distinct groups of animals with different characteristics. Mammals are warm-blooded vertebrates that have hair or fur, while fish are cold-blooded aquatic vertebrates that have scales and gills for breathing underwater.

The closest coral reef to the UK is the Lophelia pertusa reef in the North Sea, specifically in the Norwegian waters off the coast of Scotland. This cold-water coral reef is one of the northernmost reefs in the world.

Sea urchins have a hard shell called a test that protects their soft inner body. They also possess tube feet that help them move and cling to surfaces. Sea urchins are able to feed on algae and organic matter using a specialized feeding structure called Aristotle’s lantern.

To make a model of a sea urchin, you can start by shaping a round sphere out of clay or paper mache to represent the body. Then, attach smaller spheres or spiky shapes around the main body to represent the spines. Paint the model in appropriate colors and add any other details as needed.

Yes, some fish feed on coral polyps. These fish are known as corallivores and they can cause damage to coral reefs if their populations are not kept in check. Examples of corallivorous fish include certain butterflyfish, parrotfish, and angelfish.
