I doubt he's looking to put it in a tank, LOL (but maybe it'd work for an African rift tank). I think, knowing Zapins, that he's more likely to try and make a marble sculpture of a head with it. Possibly his head. :P :P :P
Besides, we have plenty of totally awesome, inert silicate rocks floating around the state to need to put one particular block of marble in a tank. I know some great collecting spots that are perfectly legal.
