wish my sand was still that white

You might buy a Sleeper Gold Head Goby (Valencienna strigata)

It feeds off the bottom as it sifts through the sand eating mouthfuls of substrate and the food that lives within the sand, keeping the substrate well oxygenated.

In this way it keeps your sand very - very white

It is a great worker, very peaceful and beautiful fish
