Under which conditions should indistinguishability of particles in a quantum gas be taken into account?

And why this affects the energy distribution of the gas

ps: this is on an old exam paper. I said that the DeBroglie wave length should be approximately equal to the spacing between the atoms, but the energy distribution bit. I'm stumped
