I want to buy a sand sifter for my 120 gallon aggressive tank but most of the gobies I've seen are all small (around 1-2 inches). Does anyone know of a large sand sifter that would be okay, meaning would not become lunch? The largest gobies I’ve seen are the dragon gobies, but I'm not they would even be big enough. The average size of the fish in the tank is 6-10 inches.
Here is a list of fish and their approx size in the tank:
V-Tail Grouper - 8"
Desjardini Tang - 9"
Magnificent Fox Face - 8"
Huge Damsel - 6"
Mandarin Goby - 2" (no one messes with him
Marine Betta - 7"
Clownfish – 6”
The other option would be to add 20-30 some nassarius snails…
