In my opinion for the fishes feel more in their real habitat and look good in a aquarium!
Aquarium live rock.
No.
from bubbles that escape from rocks or waterfalls or bubble makers that fish owners but in the tanks.
no. they live in mud.
yes. just dont put the rocks ON the gold fish...
There are pink colored rocks for fish tanks, look in the pet department or go to a store that sells aquarium supplies. Craft stores usually have colored rocks.
That depends on how big the tank is. Small tanks that are easy to carry can have most of the water removed and then be picked up and relocated. Larger tanks will need to have the fish, water, plants, rocks etc removed and then be re landscaped after it has been relocated.
they put them in their fish tanks and admire them
Fish tanks were not 'discovered' they were invented.
You can put some but not all cold water fish in tropical tanks for example you can put zebra danios and mountain minnows with tropical if you gradually increase the heat. You cannot do this with goldfish. It depends what fish you have.
yes it is
if you want fish that stays stuck on the side of the fish tank, the mud fish is the right job for it. It sucks the algae growing on rocks, sides of fish tanks or basically anything that has algae growing on it.
