Broadhead Pseudogastromyzon

Pseudogastromyzon laticeps is named for its conspicuously broad, flattened head — wider relative to body length than most other members of its genus — which increases the surface area in contact with the substrate and dramatically improves the species' adhesive performance in powerful currents. It is native to the rivers of Guangdong province in southern China, inhabiting the same type of clear, rocky, fast-flowing hill stream habitat as its congeners.

The broad head gives laticeps a notably different appearance from other Pseudogastromyzon, making it an interesting addition to a mixed hillstream display. Its patterning consists of a network of fine reticulated lines on a pale tan ground. Care requirements are similar to other Chinese Pseudogastromyzon, though the species is marginally more demanding than cheni or myersi, benefiting from a more experienced keeper's setup.

In mixed hillstream tanks, P. laticeps holds its own against other species and may displace smaller individuals from prime grazing spots, though overt aggression is uncommon. Its broader head profile also makes it visually distinctive against the more conventionally shaped hillstream species, providing added interest for the observant aquarist.

Water: 18–24°C, pH 6.5–7.5, GH 4–15, KH 2–8; high flow and excellent oxygenation; prioritise current strength and dissolved oxygen over all other parameters. Tank: 80 L minimum; smooth flat boulders and wide slate pieces; strong directional flow from powerhead or spray bar aimed along the substrate. Feeding: Biofilm, diatoms, and benthic algae; supplement with spirulina wafers and algae-based gel foods; avoid high-protein sinking pellets. Breeding: Eggs deposited under broad flat stones; condition with water changes and cooling; broad flat stones are essential for spawning site selection. Compatibility: Peaceful but may displace smaller species from grazing sites; best with similarly sized or larger hillstream loaches and cool-water dither fish.
