Hugo Kamishi Kurenai Red Aquarium Gravel 9-11mm is the ideal way to decorate and enhance your fish tank, bringing a varied range of colour and interest to your aquarium.
This gravel is suitable for all types of cold water, tropical and marine aquarium set-ups.
The gravel also acts as a good rooting medium for live plants.
Perhaps the most important function that gravel serves is to provide a home for beneficial bacteria . Those bacterial colonies are necessary to eliminate waste produced by the fish, leftover food, and plant debris in the aquarium. If the bacteria don’t have a comfy gravel bed to live in they will find other places, but may not grow in sufficient quantities to keep the aquarium safe for your fish.
If the tank is left with a bare bottom, it will be necessary to change the water more often in the aquarium to keep harmful wastes from building up. In the event the tank is heavily stocked, even frequent water changes may not be enough to keep ammonia and nitrites at bay.
Occasionally there are situations in which substrate isn’t necessary, or even desirable. The primary one is in a grow-out tank that is used to hatch eggs and raise young fry. Grow out aquariums must be kept scrupulously clean, and require frequent water changes as well as prompt vacuuming away of waste and uneaten foods.
Fry are so tiny that it is often difficult to distinguish then if they are against a gravel substrate. It is all too easy to suck them up when vacuuming the substrate, or changing water. A bare-bottomed tank makes it far easier to spot small fry, and thus avoid them when cleaning the aquarium
Hospital tanks also may not have substrate, which can harbor parasites that can linger there and infect the next inhabitant. A bare-bottomed tank is a good way to avoid that possibility. For the same reason, some owners choose to leave any quarantine tanks bare-bottomed as well.

Sand can look very nice in an aquarium and it is better for fish that dig or forage in substrates. Catfish, gobies, soles, spiny eels, and cichlids are all examples of fish that manipulate the substrate.
With sand, these fish can dig or ‘earth-eat’ without any risk or damage. Gravel wears down the barbels of catfish, and with spiny eels especially, skin wounds become a site for bacterial infections. Sand is mandatory for spiny eels and ‘freshwater’ soles/flatfish.
The particle size of sand works better for smaller fish
Plants root very well in sand
Do not use sand with an undergravel filter
Sand is much cleaner than gravel as the space between gravel pieces is big enough to allow debris in
