Bumblebee Goby

Brachygobius doriae

The Brackish Stubborn Bee (0.75 inches / 2 cm). The Bumblebee Goby is an incredibly cute, microscopic bottom-dwelling fish that looks exactly like a fat little yellow and black bee. They rest on the sand or use their fused pelvic fins as a 'suction cup' to stick to the glass. However, they are a massive trap for ignorant beginners. They are strictly BRACKISH WATER fish, and they are incredibly stubborn micro-predators that will completely refuse to eat dry pet-store fish food, preferring to starve to death.

Care and observations

The Dry Food Starvation Strike:

The Hunter's Stubbornness. THE LETHAL ERROR: Do not buy this fish thinking you can sprinkle cheap flake food or pellets into the tank. The Bumblebee Goby is an ambush predator that reacts purely to movement. If the food doesn't squirm, swim, or wiggle, the Goby will ignore it completely and slowly starve to death, turning from bright yellow to pale grey. You are REQUIRED to hatch live Baby Brine Shrimp or culture live Daphnia and Blackworms to feed them. You can sometimes trick them with frozen bloodworms if the water current blows the dead worm around to make it look 'alive'.

The Freshwater Fungal Death:

The Brackish Mandate. Pet stores constantly sell them in standard freshwater tanks. This is a death sentence. If kept in soft, acidic, pure freshwater, the Bumblebee Goby's immune system will collapse. Within weeks, thick, white, fluffy fungus (Saprolegnia) will grow all over their black stripes, eating them alive. You MUST use Marine Reef Salt to create a mildly salty Brackish environment (Specific Gravity 1.004 - 1.008) and keep the pH heavily alkaline (8.0+).

Compatibility (The Ankle-Biter):

The Tiny Terror. Do not keep them with slow, long-finned fish like Bettas or Guppies. Despite being the size of a fingernail, they are viciously territorial 'ankle-biters' and will relentlessly nip at the trailing fins of bigger fish out of pure annoyance. They are best kept in a 'Species-Only' brackish tank with many empty snail shells for them to claim as their tiny castles.
