Bull-calf Bee (Brachygobius doriae) – content, breeding

Goby Bee or Bumblebee (Brachygobius doriae)
Gunter, 1868.

The bumblebee goby or bee is a bright and interesting aquarium fish that has not recently been encountered in amateur aquariums. For a fun color, domestic aquarists called it bull-beeline.

Habitat: The coastal zone of Southeast Asia is the Malaysian state of Sarawak on the island of Borneo and is endemic to the western parts of the island plus the Bunguran archipelago, which lies west of the coast of Borneo, but is part of Riau Island, Indonesia.

The records of Singapore seem to be erroneous.

It lives in both fresh and brackish water, and is usually limited to lowlands and coastal zones, including mangrove swamps and estuaries. The bottom thus in these places, as a rule, consists of loam, sand and silt with organic material lying on the surface, such as fallen leaves, mangrove roots and submerged snags.

Some populations live in old peat swamps with water the color of tea, very low acidity, minimal conductivity and little hardness.

Example Gobie Bees from the province of Sarawak. It has a more intense color than regular yellow Brachygobius Doriae.

The bumblebee goby has a characteristic shape of the body in the form of an elongated drop oblate on the sides. The head is large in comparison with the body. Intergrown ventral fins are a kind of sucker with whose help the fish is fixed on the surfaces.

Two dorsal fins have anterior and posterior soft rays.

When creating favorable conditions for keeping the fish, very bright and contrasting colors from alternating golden-yellow and velvet-black stripes give them a resemblance to bees / bumblebees, which was the basis for the name. Some individuals have a vague dark spot on the back.

The females are larger and fuller, before spawning, they noticeably rounded the line of the abdomen. Males are more graceful and have a bright color: their stripes may not be yellow, but orange or reddish.

Goby Bee / Bumblebee (Brachygobius) – male and female.

Under natural conditions it grows to 4.2 cm, the maximum size in an aquarium is 25 – 35 mm.

Arrangement and parameters of the aquarium: for a pair of fish, an aquarium with a base size of 45 * 30 cm or equivalent is enough, or is considered minimal. With a volume of 40 liters, but, given that the bull-bee is territorial in order to avoid conflicts, it is necessary to keep a group of at least 6 individuals, which reduces the level of aggression, plus the fish become bolder and show more natural behavior.

In general, the aquarium is lost, but in the species appears in all its glory.

It is better to choose not very deep capacity, which has a large area of ​​the bottom. Be sure to have a lot of shelters of densely planted plants, so that the weaker fish did not suffer from the activity of the dominant male.

Also for these purposes snags, artificial grottoes and clay pots are suitable.

Coral sand or marble gravel can be added to the sandy ground to act as a buffer, and sea salt at a rate of about 2 grams per liter can act as water. This measure is not mandatory, although it is useful in terms of disease prevention.

Bullhead / Bumblebee (Brachygobius doriae) gets along well with peace-loving small fish hailing from tropical waters, but does not tolerate the company of other benthic species and too active and aggressive fish. The best neighbor will be Dermogenis dwarf / Poluryl fighting (Dermogenys pusillus), also preferring brackish water.

It is not ideal for a general aquarium and is best kept in the species.

Water parameters: withstand temperature drops in the range of 18-35 ° C, but optimally for the content of 22 – 28 ° C, pH 7-8.5, kH 8-20, gH 10-30.

The filtration is moderate, the lighting is diffused, the substitution of the fifth part of the water is carried out weekly.

Nutrition: prefers frozen and live food: tubule, medium-sized daphnia, Cyclops, Artemia, bloodworms. Selects food at the bottom.

From dry feed often refuses.

It is better to feed the bee goby often, but gradually.

Reproduction: breeding process Bull-calf Bee / Bumblebee It will be interesting not only for beginners, but also for experienced aquarists.

This species spawns in small caves, shelters in the form of small flower pots, ceramic pipes, shells and the like.

Spawning is possible both in a separate spawn and in a species aquarium.

If the fish live in a group, it is better to let them choose their own pair. In the pre-spawning period, they need to be strenuously and diversely fed, and the process of changing part of the water, increasing the temperature by several degrees and stimulating aeration is stimulated.

First, the male chooses a cave or other shelter for himself, diligently driving his rivals away and at the same time trying to lure the female there.

If his efforts were crowned with success, she sweeps out 100-200 whitish drop-shaped eggs with a diameter of 1 mm, and then immediately leaves, as the female will not show any interest in her offspring. The male, on the contrary, after fertilization, the caviar becomes a “caring dad” and protects it for 3-5 days until the larvae appear, but then it becomes dangerous, but rather simply not needed, since it fulfilled its mission and therefore settles.

The incubation period is 7-9 days.

Free swimming fry begins in a couple of days.

They are 16 days old, in this size they no longer need starting micro-food.

Starter feed: live dust – ciliates and rotifers. Even short-term fasting can lead to mass death of offspring.

Grown fry can take shredded tubule and nauplii artemia.

Fry Gobie Bees (Brachygobius doriae), one and two months, respectively.

Juveniles grow very slowly and only a month long with good nutrition reaches a centimeter in length. At 2 months, the behavior and coloring characteristic of adults begins to manifest itself in fish.

It reaches sexual maturity by 8-12 months.

In aquarium Bullhead / Bumblebee (Brachygobius doriae) can live 4-5 years.

Brachygobius doriae – this species is one of the most frequently available members of the genus, although confusion about its identification and natural distribution is common, and is often mistakenly confused with B. nunus or B. xanthozonus.

Brachygobius xanthozona

The genus Brachygobius currently contains 9 species described, and although all of them are referred to as Bumblebee / Bee gobies, only B. doriae and B. sabanus are usually most commonly available in trade.

Brachygobius sabanus

B. sabanus is very similar to B. doriae and these two species are most easily confused. However, in B. doriae most of the rays of the first dorsal fin and two thirds of the pectoral fin are black, while in B. sabanus the last one or two rays of the first dorsal fin are colorless and less than half of the pectoral fin are black.

Brachygobius nunus

In addition, there are, as a rule, small dark “saddles” between the dark strips of the body in B. sabanus, which, as a rule, are absent in B. doriae, and there is a significant difference in the maximum size between them B. doriae is much larger.

Brachygobius Spec.

B. nunus comes from India, Sri Lanka and Bangladesh and has 4 relatively thin dark stripes on the body, rather than three broad stripes, visible in B. doriae and B. sabanus.
