Brachygobius doriae | Pictures
Synonyms: Gobius
doriae
Physical description: A small, squat species that has a laterally compressed rear region.
There are two dorsal fins and the caudal
fin edge is rounded.
The color and band number is variable, although the yellow-gold to copper body is usually
marked with four, broad black bands.
The dorsal, pectoral, pelvic, and anal fins are black, while the caudal
fin may be black to copper.
The bands lessen in width with age.
Size/Length: To 2" (5 cm)
Similar species: Bumblebee Fish (
Brachygobius xanthozona ) found in fresh and brackish
waters of Borneo, Java, Sumatra, Thailand, and Vietnam.
Another Bumblebee Goby (
B. nunus ) inhabits similar habitats.
Habitat: Asia; fresh and brackish water in Borneo, Java, India, Malaysia, Sumatra, and Thailand
S: bottom
Aquarium: A 16" (40 cm) or 5 gallon (19 L) tank is sufficient.
A shallow, wide tank is preferred.
Provide
a retreat for each fish with rocks, wood, pipes, shells, and roots.
Use plants that can tolerate brackish
water.
The substrate should be sand, although fine gravel is acceptable.
Water chemistry: pH 7-8.5 (7.5), 10-30 dH (14), 75-86°F (24-30°C).
A 1-1.5% addition of salt is recommended.
Add
7.5-11 tsp. of salt for every 10 gallons (10-15 g/10 L).
Social behavior: A peaceful, quiet fish that can be kept in a brackish water tank with small to medium
sized fish.
This species is very territorial towards others of its own species, although suggest keeping it
in groups as this disperses aggression.
Suggested companions: Glass fish, Livebearers, Halfbeaks, Rainbowfish
FOOD: Live; worms, insect larvae, crustaceans; tablets
Sexual differences: Males are more colorful, while females are plumper.
Breeding techniques: A pair should be kept in a clean, brackish water tank.
The addition of fresh water, coupled
with a slight increase in temperature induces spawning.
The female has a visible ovipositor two to three days prior to egg
laying.
From 150-200 eggs are laid in snail shells, under rocks and roots, and in crevices.
The
eggs hatch in 4-5 days and the male guards the brood.
Start feeding with roftiers and later with
Artemia nauplii.
The fry first swim in the middle water
levels before becoming substrate dwellers.
Breeding potential: 6.
Breeding is not difficult under the proper conditions.
REMARKS: This Goby can be slowly acclimated to fresh water, although prefers brackish.
Males
and females undergo a color change at spawning times when the front half of their body darkens.
Difficulty of care: 5.
This brackish water species requires live foods and peaceful companions.
This Goby is sensitive to changing water
conditions.

Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Developpement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.
