Brackish gobies taxonomically belong to the Gobiidae family within the order Gobiiformes. Most inhabit intertidal zones, estuaries and mangroves prone to significant salinity fluctuations rather than stable fresh or marine zones. Brackish gobies demonstrate a wide array of body shapes, color patterns and behaviors.
Introducing Brackish Gobies
- Origin: Intertidal zones worldwide, especially Indian Ocean/West Pacific
- Size: Most under 4 inches, down to less than 1 inch
- Lifespan: 2-5 years depending on species
- Temperament: Variable temperaments – peaceful to aggressive
- Appearance: Elongated bodies, large fused dorsal fin, pelvic suction disc
- Varieties: Violet gobies, dragon gobies, shrimp gobies, eel gobies
- Price Range: $8 – $25 each
Habitat & Tank Requirements
- Natural Habitat: Brackish intertidal zones, estuaries, mangroves
- Minimum Tank Size: Species tanks from 10-30 gallons
- Water Parameters: SG 1.005-1.010, temp 72-82°F, pH 7.5-8.5
- Tank Setup: Mix of fine sands and rock rubble, anchored wood, moderate lighting
- Diet: Carnivores accepting live, frozen, pelleted meaty foods
- Feeding: Forage along bottom for food, some midwater feeders
- Foods: Live/frozen brine shrimp, blood worms, mysis shrimp, black worms, quality flakes
- Reproduction: Substrate spawners, no parental care. Serial spawners.
- Breeding Conditions: Condition fish beforehand with diverse meaty foods. Lower water level and add fine-leafed plants, caves and mesh substrates for spawning sites while maintaining brackish conditions. Leave with breeders until eggs hatch. Move fry to separate rearing tanks.
- Spawning Process: Diminutive adhesive eggs with filaments laid in small clusters or strings attach to surfaces. Hatching occurs in 14-21 days, after which tiny transparent fry become free-swimming within a few days. Offer infusoria, then newly hatched brine shrimp once large enough to accept them.
Generally hardy when maintained in appropriate brackish water conditions. In fresh water prone to bacterial, parasitic and fungal disorders. Use quarantine for new arrivals. Increase aeration. Utilize appropriate medications if required while monitoring for signs of stress and reducing every other environmental stressor.
- Compatibility: Species specific tanks ideally recommended
- Care Requirements: Maintain specific gravity and alkalinity, frequent testing
- Legalities: None
Suitable Brackish Tank Mates
Selected mollies, archerfish, scats, monos, knight gobies. Avoid mixing shrimp & dragon gobies.
Difficult to discern visually in most species. Males smaller with more intense coloration. Gravid spot visible in breeding females when carrying mature eggs.
How many species of Brackish goby?
Over 130 brackish-adapted goby species have been documented, with many others likely unknown. Those available and best suited for home aquaria represent only a small fraction.
How to feed Brackish goby to make their color brighter?
Feed a mixture of live, frozen and dry foods selected from recommended varieties to provide balanced nutrition and really enhance natural vibrancy.
How Big do Brackish goby Grow?
Maximum sizes range under 1 inch for the dwarf varieties to over 4 inches for the largest dragon and violet gobies. Most hover in the 2-3 inch range once mature.
How fast do Brackish goby grow?
Growth rate varies by exact species. Most reach their max size within a year when given optimal brackish water conditions and sufficient diet.
How long do Brackish goby live?
Average reported lifespan is 2-4 years. A few of the hardier shrimp and knight gobies have lived over 5 years in well-maintained brackish tanks.
How to take care of Brackish goby?
Maintain specific gravity between 1.005-1.015, alkaline pH 7.5-8.5, stable warm temps and excellent filtration suited for brackish tanks. Feed diverse meaty foods and monitor water parameters vigilantly.
Which food products are the best for Brackish goby?
Live blackworms, frozen mysis shrimp, Hikari marine gourmet frozen food mixes, cobalt aquatic brine shrimp pellets.
Is good to keep Brackish goby as pets?
Yes, for fishkeepers interested in setting up specialized brackish systems. Their diversity offers selections for any skill level able to provide species-specific care requirements.
Why my Brackish goby die?
Fluctuating or inappropriate salinity levels, pH crashes, aggression from tankmates, poor diet and water quality all shorten lifespans. Meet all environmental needs.
Are Brackish goby aggressive?
Some species show intra-specific aggression while others harm tankmates. Dragon, darter and sleeper gobies tend to show the highest aggression risk. Avoid mixing them with docile species.
Do Brackish goby kill other fish?
Though rare between properly matched species, male dragon gobies may harass slower moving tankmates to the point of secondary health complications leading to premature death in extremely confined quarters.
