    Gobioides broussonnetti - Violet Goby

    [picture]

    Scientific Name: Gobioides broussonnetti
    Common Names: Violet Goby, Dragon Goby
    Care Level: Medium
    Adult Size: 55cm (21")
    pH Range: 7.8-8.4
    Temperature Range: 23-25*C/73-78*F
    Specific Gravity/Hardness Range: 1.005-1.020
    Origin/Habitat: Estuarine brackish areas, western Atlantic coastline from South Carolina south to southern Brazil, including Gulf of Mexico
    Temperament/Behavior: Peaceful fish, despite aggressive appearance. Filter feeder, requires small-sized food. Small eyes and poor eyesight indicative of non-predatory nature. Good community fish, prefers tight, dim hiding places to lurk. Mostly nocturnal feeder.
    Compatible Tank mates: Other BW community selections - mudskippers, bumblebee gobies, mollies, chromides, although can be aggressive toward conspecifics.
    Diet: Often only takes frozen-thawed foods such as bloodworms, brine shrimp and mysis. Difficult to switch to prepared foods. Depending on aggressiveness of eating habits of tankmates, may require spot feeding. Target feeding after lights out proven to be effective.
    Tank Size For Adult: Generally viewed as an inactive fish, but large adult size warrants 75-90gal tank as adults. Relatively slow growing after 7-8" size is attained.
    Narrative: Like many brackish fish, often sold as a freshwater specimen. G. broussonnetti can live for abbreviated periods of time in full freshwater, but often develops skin ulcers and immune deficiencies when kept in freshwater long-term. If purchased in freshwater, transition to low-end brackish via slow drip acclimation should be relatively straightforward. A fine substrate such as sand or mud will be appreciated as they will filter-feed by sifting through substrate for small food particles. Long caves such as tubes of PVC will be appreciated for lurking during the daytime. No sexual dimorphism is noted.

    Brachygobius xanthozonus - Bumblebee Goby

    [​IMG]



    [​IMG]

    Scientific Name: Brachygobius xanthozonus
    Common Names: Bumblebee goby
    Care Level: Medium
    Adult Size: 3.8cm TL (1.5")
    pH Range: 7.8-8.2
    Temperature Range: 25-28*C/75-82*F
    Specific Gravity/Hardness Range: 1.005-1.012
    Origin/Habitat: Estuarine areas, brackish mangrove swamps in Sumatra, Borneo, Java
    Temperament/Behavior: Peaceful community fish. Does well in groups.
    Compatible Tank mates: Other BW community selections, nothing aggressive enough to eat a fish of its small stature. They can also be easily outcompeted for food, so care must be taken to ensure they are getting enough to eat.
    Diet: Often requires small live foods such as blackworms and baby brine shrimp. Can possibly be weaned onto frozen foods such as mysis, brine shrimp and bloodworms.
    Tank Size For Adult: A small group of adults can be kept in tanks as small as 5 gallons.
    Narrative: These fish are often sold as freshwater specimens. The adults may travel to FW to spawn, then return to brackish environments. They seem to do best in low-end brackish for long term care. They do well in tanks with lots of cover. Large snail or barnacle shells work well. NOTE: There are several similar species imported under the name "bumblebee goby". B. xanthozonus is one of the more common ones; telling them apart is next to impossible without the use of a microscope. However, the care listed above can be considered a broad guide for this group of fish.
