Identification Members of the genus Pseudolaguvia are small erethistid catfishes inhabiting hill streams and large rivers in the area bordered by the Ganges River drainage (northern India) to the west and the Sittang River drainage (east-central Myanmar) to the east. They can be distinguished from other sisorids by their small size,a combination of a thoracic adhesive apparatus with a median depression and prominent postcoracoid processes.

Pseudolaguvia spicula differs from congeners except for P. inornata, P. kapuri, P. tenebricosa,P. tuberculata and P. virgulata in having a deeper caudal peduncle (7.9–9.6% SL vs. 5.0–8.1). It is distinguished from P. inornata in having shorter dorsal- (11.6–14.3% SL vs. 18.6–21.7) and pectoral-fin spines (15.7–17.4% SL vs. 20.4–23.3) and indistinct, pale vertical bands on the body (vs. bands absent), and from P. kapuri in having a shorter dorsal-fin spine (11.6–14.3% SL vs. 14.0–15.5), shorter adipose-fin base (14.7–17.1% SL vs. 17.1–18.9), and narrower head (19.2–22.6% SL vs. 23.4–24.0). Pseudolaguvia spicula differs from P. tenebricosa in having shorter dorsal- (11.6–14.3% SL vs. 15.8–17.3) and pectoral-fin spines (15.7–17.4% SL vs. 18.7–20.4) and a shorter caudal fin (24.2–27.5% SL vs. 28.5–31.2), from P. tuberculata in having a shorter snout (48.6–51.9% HL vs. 52.1–55.5), larger eye (10.6–13.9% HL vs. 8.8–10.4) and shorter pectoral-fin spine (15.7–17.4% SL vs. 18.3–20.1), and from P. virgulata in having shorter dorsal- (11.6–14.3% SL vs. 21.5–24.0) and pectoral-fin (15.7–17.4% SL vs. 28.5–29.1) spines and caudal peduncle (15.4–17.9% SL vs. 18.2–20.2), a smooth (vs. serrated) anterior edge of the dorsal-fin spine, the presence of pale vertical bands (vs. pale longitudinal stripes) on the flanks and the absence (vs. presence) of a pale yshaped marking on the dorsal surface of the head and supraoccipital process.
Sexing Not known.
General Remarks It is very likely that this species has not been exported for the trade as yet but general care will be very similar to that of other Pseudolaguvia species.

Jump to next section Husbandry Information
Feeding Is known to take only live food like blood worms, frozen brine shrimp etc. Spot feeding will help in case tank mates are voracious feeders.
Furniture Fine sand for the bottom and smooth pebbles / rocks. This species was collected from shallow streams with a moderate to strong current and a substrate of sand, pebble and rocks.
Compatibility A peaceful species suitable for a hillstream biotope.Extreme care should be taken while choosing their tankmates as these fish are extremely poor at competing for food.
Suggested Tankmates Cyprinids like Barilius and Danios and Balitorine loaches like Homaloptera species. Other fish species found in the same habitat include Psilorhynchus sucatio ,Glyptothorax botius ,G. telchitta and Pseudolaguvia virgulata.
Breeding Unreported.
