Golden Head Goby

Hi All:

I am interested in a golden head goby. I am hoping that he will be a sand sifter and algae eater.

His tank and mates would be:

Ammonia-0
Nitrite-0
Nitrate 5-20 depending
pH-8.2
Sal. 1.023-1.025 depending

92 gallon corner bow front
25 gallon sump
skimmer
3 power heads
30lbs LR
1-1.5" sandbed
UV sterilizer

2 Ocellaris clowns
3 blue/green chromis
1 cleaner shrimp
1 male purple eye/lyretail anthias and 2 females
1 red flame angel

ANY THOUGHTS?
