Sand sifting goby- which one?

[1bigstud]

I've got a golden head goby (yellow head white body that u mentioned earlier) These do a great job cleaning up sand but do spread alot of sand around your tank. Also these are hard to keep alive and I would only recomend them in a mature tank of atleast 70 gallons. If u dont mind the mess they make and can keep one alive it would be well worth it, this is a very interesting fish.
