You usually find bumblebee gobies on the market somewhere near an inch in size.

Bumblebee Gobies. Everyone loves the little bumblebee gobies, but not everyone wants to go to the trouble to take care of them. Unfortunately, bumblebees usually fall into the hands of small tank owners -- not a good mix. Bumblebees can live in small tanks, but most small tank owners lack the experience to keep these cute little dudes alive and kicking..

Less than an inch long. Maybe the little bumblebee gobies are blurry? Pale colors at first.

Species. Several types of bumblebees pop up from time to time -- much depends on where they came from. Some sport different bar patterns. Different species? Machts nichts. You keep them all the same way. We like the four-barred ones. The different species have different numbers of rays in their various fins. As the famous ichthyologist, Elizabeth Barrett Browning said, “How do I i.d. thee, let me count the rays.”

Feeding Time. Your new bumblebee gobies probably will ignore flake foods at first. They prefer live foods (like blackworms) or at least frozen shrimp (thawed, of course). Lots of other frozen bug-size foods trip their triggers -- especially when other bees compete with them. If you keep a few large female guppies with them, your bees will find some live food on their own. Too large a fish will intimidate them. They have a big mouth for their size, so we plan to experiment with glassworms. California blackworms go down very smooth.

Most bumblebee gobies ignore the flakes and snap up live brine shrimp.

Mixers. Bumblebee gobies move slow, so leave out the speedy zebras and other zippers. Good candidates include other brackish fishes such as glassfish (Indian), flounders, and dragon gobies. Mollies like the same water but get to the food too fast and stuff their guts while the bees just haven’t quite got the buzz yet.

Scavengers. Since snails hate salt and catfish don’t like it much either (except bull sharks), we’d recommend ghost shrimp as scavengers. If you feed flakes, these semi-invisible arthropods will make excellent cleaners.

Freshwater flounder plastered onto tank side. Good tank mates with bumblebee gobies.

Bumblebee gobies have a good-size mouth for such a little runt.

Fierce Little Beasts. From the front, bees look to be all mouth -- especially when yawning, eating, or arguing during spawning. Bumblebee gobies can nip long-finned fishes.

Plant here is Java moss. Java lance fern also works for bumblebee gobies..

Plant Decor. Salt in their water puts the kibosh on most plants. Plastic plants always work. Some of the best live plants to keep with bumblebee gobies include Java moss, the slow-growing Java lance fern, and the fast-growing water sprite.

LA
Both these species demand live foods at first.

Comfort Decor. PVC pipe pieces and resin caves on the bottom serve as security and breeding sites. More natural choices include empty snail shells (not little shells, tho). Look into those shells available for hermit crabs. Axelrod’s Atlas of Freshwater Fishes has some great bumblebee goby shots with the little twits defending their snail shell homes and hearths. They look like fierce wee beasties with their huge (comparatively) mouths ready to bite whatever approaches -- mostly other male bees.

LA
What a huge mouth. Eats the same small foods that bumblebee gobies eat.

LA
Hard to believe they eat the same foods and co-exist in the same tank.

After a few good meals bumblebee gobies start getting a bit of a gut -- and way better colors.

LA
"Que pasa?, good buddy?"

LA
Bumblebee gobies do mix with other fish. All three species thriving together.

We'll try to catch them spawning later.

Just a reminder of how small these bumble bees are. That's a female mollie in with them.


Bumblebee Goby

Brachygobius Xanthozona


Overview:

    This popular little Goby is available from time to time. It is a brackish water fish that is not suited for a freshwater set up. Given proper conditions this fish can make an interesting addition to your brackish tank.

    Listed tank sizes are the minimum
    Size: 1¾ inches , (4.5cm) Same for both sexes
    Tank: 20 gallons, Brackish water
    Strata: Mostly Lower, will visit all levels
    PH: 7.5 to 8.5
    Hardness: Mediun hard to hard
    Temperature: 75°- 86°F (24° to 30° C)

Classification:

    Order: Perciformes
    Suborder: Gobioidei
    Family: Gobiidae
    Genera: Brachygobius
    Species: xanthozona



Common name:

    Bumblebee Goby , Bumblebee fish

Bumblebee Goby
Distribution

    Western Indoneasia, Thailand, South Vietnam. Mostly in estuaries.



General Body Form:

    Elongated and round. Typical for the family the ventral fins are fused together to form a suction disc. There are two Dorsal fins separated by a wide indentation. The rear dorsal is located above a similar shaped anal fin. The back portion of the tail fin is rounded.


Coloration:

    The Basic background color of the the Goby is a pleasant Honey Yellow or mustard color. This color is marked with a series of Black vertical band and spots. Usually there are four main bands, The first runs over the fishes head near the eye. The next two bands cove the body and slightly on the fins. The final band ends at the start of the tail (caudal) fin. In between the bands There can be less pronounced Black spots. As the fish ages the Black tends to fade and the Yellow becomes more pronounced.


Maintenance:

    Feeding your gobies will be the most difficult part of maintaining them. They will eat only live food such as Brine shrimp, Daphnia, Cyclops and Mosquito larvae. Some have had success in getting the fish to eat frozen, however they seem not to recognize it as food unless it is moving. Although they can be kept in a community setting with other salt tolerant species ( Mollies or Platies ) they will remain shy and not flourish. They will be happiest in a species tank. Keep a fairly large number, ten or more, in the tank and provide plenty of hiding places such as stones tubes and caves. Plants will be limited to salt tolerant varieties and probably the best choice will be the die hard Java fern, plastic may be a better choice. The water should have a small amount of marine mix to increase the salinity. One to two teaspoons per two gallons should be OK. Although you do not want heavy circulation, aeration and filtration should be efficient.


Biotope:

    Brackish estuaries with plants as well as open areas of Southeast asia

Breeding:

    Not one of the easier fish to breed. Condition the fish well with a varied diet of small live foods such as mosquito larvae, brine shrimp and Daphnia. I has been reported that breeding can be initiated by the addition of some fresh water to the tank. You should be able to tell when the fish are ready when the females become visibly plumper and male's black bars almost disappear. The eggs are usually laid in flower pots, under rocks or in caves. The eggs are guarded fiercely by the male. In four to five days the eggs will hatch. The fry are very difficult to feed and should consist of liquid foods (infusoria ) and then baby brine shrimp. Once hatched you should move the parents as they tend to eat the young. The young will swim in all strata of the tank and after four to five weeks settle on the bottom and start to take on the adult coloration.
