Rocks are added to aquascape/landscape a tank. They can be used in many ways to suit your own design. I often use them to build retaining walls and bank gravel up behind them to make several different levels in a tank. They can also be placed one on top of several to make caves or tunnels etc.
Its the rock, sand, gravel, whatever on the bottom of an aquarium.
yes. "Sometimes live rock is inhabited by nasty critters that can chew on coral or even kill fish. To prevent these creatures from getting into your aquarium, you can dip the live rock in high salinity water or freshwater. After dipping, the organisms will likely flee the rock and enter the water, where they can be sorted and you can add what you want to the aquarium. Mantis shrimp and certain crabs are the most frequent aquarium pests, so be on the lookout for these particularly."
Add an aquarium heater. Make sure you choose a heater with the correct wattage for your aquarium's water volume.
Yes, aerator and plants are important in the aquarium to add oxygen in the water for the animals there in.
yes you can
you can arrange your aquarium anyway you want but i would add a little castle or something for the fish to hide in.
you add the fish to the tank and it will just show up.
River rock seems to be common but I prefer the look of Pagoda and lace rock.
