First, a little about Sleeper Gobies:

Sleeper gobies belong to the family Eleotridae. They are not true gobies, which are from the family Gobiidae. Sleeper gobies have seperate ventral fins, whereas in true gobies, these fins are combined to make a cup-shaped sucker. This rather odd fish has two dorsal fins.

Most sleeper gobies are found in brackish to fresh waters throughout the world, although some species are only found in fresh water. Some are predators, some feed on plankton.

Depending on the species, spawning methods vary. The genera Dormitator and Mogurnda spawn in a similar way to cichlids, depositing eggs on stones and wood. Eleotris spawns among fine-leaved plants, with males undertaking limited brood care, fanning the eggs with their pectoral fins and keeping the newly hatched fry together. The young are free-swimming initially and assume the bottom-dwelling havits of the adults later on.


The Marbled Sleeper Goby:

The Marbled Sleeper Goby, Oxyeleotris marmoratus, is one of the larger Gobies, growing up to 20". It is a nocturnal hunter, and inhabits slow-moving bodies of fresh water. During the day, it hides among bogwood and rocks, where its camouflage marbled coloring comes in handy. Provide this fish with plants, wood, rocks, and a soft substrate where it will dig when hunting for food. Because of this, a good filtration system is needed.

The Marbled Sleeper Goby is a greedy fish and can consume its own weight in food every day. It will eat virtually anything from meaty foods to insect larvae to live foods.
