Fish do not care how long you spend decorating their tanks they just want to move the rocks. They do this because they check the rock to see if there is any algae or other feeding substances by putting it in their mouth.
Various reasons; perhaps to shovel & excavate to make a 'nesting depression', or to examine it for nutrients to feed on.
It shouldn't be eating rocks ! If it is - there's something seriously wrong, and it should be taken to a vet !
They hire a contractor.
it depends if the turtle is small if its small it can live in small places example a small fish tank with some rocks in it a big turtle should live in a large tank with rocks in it
It is natarul for turtles to lie on rocks and such.
For a land tortoise, you will need a UV light (that provides artificial sunlight), Vegetables, substrate (dirt), and a hiding place. For water turtles You will need all this + bugs and water.
No, not really, you need mostly water and a few rocks out of the water to bathe on, a big tank depending on how many turtles you keep, because they get BIGGER than you think they do! you also need a light and no other smaller fish with it.
no, they can't
About a 20 gallon tank.
Depending on the species, one or two. Turtles will keep growing through their entire lives, overcrowding or expecting them to only grow to the size of the tank is something that usually leads to dead turtles.
Yes, they will eat any small pebbles. This may cause digestion blockages and can be FATAL. When putting gravel/pebbles into a turtle tank, make sure they are at least 2cm big.
I think it depends on how big the turtles are.
they move by turtles
No.
Tapping on the glass of the tank !
