Growth rates depend on how water changes in your tank water quality . Fresh water input and good appetite , fish would grow fast !!!! .
Caresheet for Marble Goby
- Thread starter MarbleGoby
- Start date
I have two that are in the 11-13 inch range that I have also had for about two years. They were a about two inches when I got them.In my experience they can be very prone to fungal infections up intill the 4 inch range.After that they are pretty much bullet proof.In the wild they are found in pure freshwater also so you do not need to add salt to there tanks. In the past I have had some that I have raised up to the 19 inch mark always in pure freshwater feeding them raw shrimp,silversides and large nigthcrawlers.
Its very interesting to see every one grow marble goby to mature size but i more interested if some one can tell me how to distinguish its gender the procedure breeding them.Thank you.
My Goby is still doing nicely. He's about 10" or so, I think.
Keeping him fat and happy on a diet of night crawlers, silver sides, and gold fish.

Family: Eleotridae
Distribution: Thailand, Cambodia, Laos, Vietnam, Indonesia, Malaysia, Phillipines, Brunei Darussalam.
Habitat: Occurs in various biotopes, including rivers, ponds, swamps and flooded forests. It generally prefers areas of little or no water movement. Mainly found in freshwater but is also found in brackish environments.
Maximum Standard Length: 26" (65cm), usually smaller in aquaria.
Minimum Tank Size: A sedentary species, so a tank measuring 60" x 24" x 24" (150cm X 60cm X 60cm) - 565 litres ought to be enough for all but the very largest specimens. Young fish can obviously be grown on in smaller tanks.
Tank Setup: The fish like to dig, and sometimes partially bury themselves, so a soft substrate of sand, several inches in depth is recommended. Provide hiding places using large chunks of bogwood, lengths of plastic piping, or clay flowerpots. Dim lighting is also preferable, as this is essentially a nocturnal species.
Temperature: 72-82°F (22-28°C)
PH Range: 6.5-7.5
Hardness: 10-15°H
Diet: Although strictly carnivorous in nature, many captive specimens can be trained to take dried pellets. It should definitely be offered a meat-based diet, however. Young fish will accept bloodworm, small earthworms etc., while larger fish will take whole prawns, large earthworms, lancefish and other similar foods. Take care not to overfeed as these fish are very greedy indeed.
Compatibility: Territorial with its own kind and will consume any fish it can fit in its capacious mouth. It is therefore best kept alone, although we have seen large specimens coexisting with other similarly-sized fish that inhabit other parts of the aquarium, such as arowana. Obviously, a very large tank would be required if this is to be attempted.
Sexual Dimorphism: Male fish have a longer anal fin and more extended second dorsal fin. Apparently the genital papilla is also more pointed in the male than in the female.
Breeding: Not thought to have been bred in captivity. Any attempt would surely prove problematic, due to the adult size of the fish and their territorial, predatory nature.
Notes: One of the largest goby species in the world, O. marmoratus is unsuitable for the vast majority of aquaria, but is an interesting oddball for the true enthusiast with the facilities to house it properly. It is a nocturnal ambush predator and generally remains motionless during daylight hours unless striking at food. It is a popular food fish in some of its native countries, where it is known as soon hock.

Good caresheet except for the min tank size if you plan on tankmates im upgrading from 125 to a 240 as we speak, and the part about not breeding in captivity i have a breeding pair now. Good info
Hey rivershark have you ever seen any sleepy cod (oxyeleotris lineolatus) for sale out on the west coast.
