MARBLE SLEEPER GOBY This is my current male around 18 inches now and my current 15 inch breeder female. These are old photos of my first MARBLE SLEEPER GOBYS that i got around 1991-92 this pair never got over 12 inches, they spawned a couple times but the eggs never hatched. I have always had MARBLE GOBYS since i got this first pair, hands down my all time favorite fish.
