| Species Information | |
| Size | 75mm (3") SL. Find near, nearer or same sized spp. |
| Identification | The erethistid catfish genus Hara consists of small to medium sized catfishes with a brown cryptic coloration and heavily
tuberculate skin.Species of Hara are diagnosed from other members of the family in having an anteroventral flange on the ventral surface of the complex centrum and the parapophysis of the fifth vertebra with a vertical lamina (de Pinna, 1996). The genus has been recorded from the Ganges-Brahmaputra river drainages eastwards to the Salween River drainage in western Thailand (Hora, 1950; Kottelat, 1989; Ukkatawewat & Vidthayanon, 1998).
Hara filamentosa can be distinguished from congeners (except H. mesembrina and H. longissima) in sometimes having (vs. always lacking) a filamentous extension to the first principal ray of the upper caudal-fin lobe; it is also distinguished from all congeners except H. hara and H. longissima in having a short posterior process on coracoid (reaching to midway of distance between bases of pectoral spine and first pelvic-fin ray vs. two thirds or beyond; length 19.9-22.8% SL vs. 23.5-38.3). It differs from H. longissima in having a shorter (length 14.9-17.8% SL vs. 18.8-21.3) and deeper (depth 6.1-7.2% SL vs. 5.0-6.1) caudal peduncle (depth 2.1-2.9 times in its length for H. filamentosa vs. 3.1-3.9 times in H. longissima) and deeper body (depth 13.9-19.2% SL vs. 12.5-14.5). Hara filamentosa can be further distinguished from H. hara in having a longer adipose-fin base (15.7-21.7% SL vs. 11.8-15.6),deeper caudal peduncle (depth 6.1-7.2% SL vs. 5.0-5.8) and lacking (vs. presence) of serrations on the anterior edge of the dorsal spine, from H. horai in having a deeper caudal peduncle (depth 6.1-7.2% SL vs. 5.2-6.2) and a shorter adipose-fin base (length 5.7-21.7% SL vs. 10.0-13.7) and head (length 26.5-29.1% SL vs. 30.3-34.2), from H. jerdoni in having a shorter pectoral spine (length 23.3-29.9% SL vs. 42.2-51.7), more soft pectoral-fin rays (total number of soft fin rays modally 7 vs. 5), more vertebrae (31–34 vs. 27-29), the supraoccipital spine not reaching (vs. reaching) the anterior nuchal plate and a deeply forked (vs. emarginate) caudal fin. It differs from H. mesembrina in having a shorter caudal peduncle (length 14.9-17.8% SL vs. 17.2-18.9), from H. minuscula in having more soft pectoral-fin rays (total number of soft fin rays modally 7 vs. 5) and the supraoccipital spine not reaching (vs. reaching) the anterior nuchal plate, and from H. spinulus in having a longer dorsal spine (length 20.4-27.6% SL vs. 14.7-19.8), adipose-fin base (length 15.7-21.7% SL vs. 12.9-16.1) and caudal peduncle (length 14.9-17.8 % SL vs. 11.8-15.0). |

| Husbandry Information | |
| Feeding | All Hara are known to take prepared food but prefer live food like bloodworms, frozen brine shrimp etc. May need some effort to gradually get weaned off live foods. Spot feeding will help in case tank mates are voracious feeders. |
| Furniture | Fine sand for the bottom and smooth pebbles / rocks. This group of fishes will appreciate some amount of plant cover too. |
| Compatibility | A peaceful species suitable for a hillstream biotope. |
| Suggested Tankmates | Peaceful Cyprinids like Puntius and Balitorine loaches like Schistura or Nemacheilus species. |
| Breeding | Unreported. |
