Overview
The Lumbantobing goby is a quiet little lowland goby for a small, gently flowing tank. It is a step up from the easiest fish.
Did you know
The Lumbantobing goby reached European fish tanks before it had a scientific name. It was traded simply as an unidentified orange-spotted goby until it was described in 2017.
Caring for the Lumbantobing goby
Keep Lumbantobing gobies as a small group in at least 11 gal (40 L), with gentle flow and plenty of cover. A soft substrate suits them. Males are mildly territorial, so split the floor into little territories with leaf litter, wood and stones.
Keep the water warm, soft and slightly acidic, at 75 to 82°F (24 to 28°C) and a pH of 6.0 to 7.5. If you like, tint it lightly with wood or leaves until it is gently tea-stained.
Lumbantobing gobies stay near the bottom and take small meaty foods. Offer frozen and live items such as cyclops, baby brine shrimp and finely chopped bloodworm, alongside small sinking foods.
They are mostly peaceful and social. Give them calm, small companions that will not steal their share. There is no established record of the species being bred in an aquarium.
Good to know
Pseudogobiopsis lumbantobing is a member of the family Oxudercidae, described by Larson, Hadiaty and Hubert. It honors the ichthyologist Daniel Lumbantobing, whose specimens finally settled its identity. It is also known as the Sumatra dwarf goby.
In the wild
In the wild, the Lumbantobing goby lives in gentle lowland streams and rivers on Sumatra and Java in Indonesia. It keeps to sand, gravel and rock at very low elevations, often among algae and aquatic plants.
