"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."

Sleeper Gobies are also called Gudgeons, and are not true gobies. They're an interesting group of fish, including some very beautiful small species. Peacock Gudgeon and Purple-Spot Gudgeon are both breed commercially, and can be found with a little searching. I used to breed Peacocks.

Knowing it's size and how much it eats, I think you'd go broke trying to feed it shrimp pellets. I would start culturing red worms (which is very easy to do) and plan on feeding it chopped fresh fish, shellfish, etc. Whatever is fresh and on sale in the seafood dept. Canned salmon packed in water will work as well. Frozen foods like bloodworms, brine shrimp, mysis shrimp, and squid are all excellent too. If your LFS carries blackworms, they are a good food as well, but must be kept in the fridge and rinsed daily.

DO NOT OVER FEED!!! This is very important with any carnivore that eats a lot. Also, do not feed beef heart (occasionally is ok, once/month or less) or other red meats. Feeder fish are not very nutritious, and can carry parasites.

Give this fish room to grow, no less than a 48" tank, it gets 20" long. (personally I would probably move it to a 96" or bigger once it grows to 10-12") Weekly water changes are important as well, 25% or more. Very fine gravel or sand will allow it to dig food out of the substrate.

I've included a link to buy some red-worms, but if you head to the vermiposting forum I'm sure they can give you lots of sources for them. Red-worms are one of the best fish foods IMO, as they can be fed to almost any fish since you can find baby worms and adult worms easily. I culture them in a standard fish shipping styro box from my LFS. You could probably get one from a Vet as well. Rubbermaid and similar boxes can also work.

Thank You Nick.

Is it any better if I raise my own feeders? I have goldfish and rosy reds outside and guppies (3 adults and four fry) and platies (one very pregnant) in my other tank. I was hoping they'd help control population overflow but if it's really not good for them...

It's one of the reasons I wanted a predator I end up with too many goldies at the end of the year and the petshop won't take them for free...One year I had 80 babies and 10 that still made it through winter outside.

I got some blackworms for the time being (they hardly touch them) so of course they finally started eating the zebra danios I bought with them. My petshop doesn't sell guppies anymore they sell young zebra fish instead which was a great deal when they had zebras, guppies, and whiteclouds (only zebras now) in the tank for ten cents and I was looking for little fish for my other tank but I have my doubts about them being easy feeders to catch. I had 15 in there and then 7 dissapeared in one night so maybe my little big men just aren't that hungry..

i have a marbled sleeper goby living with a dinosaur bichir. they were b oth 3 in. long when i got them and they are fairly good tank mates, the bichir swims around and lays against the goby and i have no incidents between the two. the bichir however has body armor for scales and that may work out in his favor. my bichir is no about the size of a regular sharpie and the goby is 9 in. and about 2 1/2 inches across, even though there is an enormous size difference the goby doesn't attack the bichir.

I have many marble goby fish i am in
