Eponymy: Mr Vicky ‘Athu’ Atukorale (fl. 1965) was a Sri Lankan naturalist who first drew Deraniyagala’s attention to this fish. He wrote: Notes on Birds Collected at Kumana Sanctuary on 17th May, 1949 for the Dehiwela Zoo (1949). An amphibian is named after him. (Ref. 128868), visit book page.

背的软条 (总数) : 10; 臀鳍软条: 8; 脊椎骨: 24 - 26. Horadandia atukorali differs from its congener H. brittani by having a more slender body (depth 24.6-29.8 % SL, vs. 27.7-31.9); dorsal profile of head slightly concave (vs. straight) behind level of eye; a greater eye diameter (37-41 % HL, vs. 27-37); origin of dorsal fin slightly posterior to (vs. distinctly behind) origin of pelvic fin; pelvic fin reaching beyond anal-fin origin (vs. just reaching anal-fin origin); origin of dorsal fin located halfway between snout tip and hypural notch (vs. closer to hypural notch); one (vs. none) lateral process on each side of kinethmoid; anterior end of kinethmoid narrow (vs. wide); palatine process of maxilla acute (vs. obtuse); and supraorbital length ~50 % of orbit diameter (vs. ~44 %) (Ref. 94541).
Body shape (shape guide): fusiform / normal.
Inhabits still or slow-moving water, frequenting swamps, rice fields and similar still waters. Found in weedy ponds of coastal plains (Ref. 4832). Common in less saline mangrove swamps and in less polluted canals. Often encountered together with Aplocheilus. Feeds on insects.
栖息于静止的，否则缓慢移动的水, 常出现于沼泽，稻田与相似的静止水域。 发现于海岸平原的杂草丛生池塘了。 (参考文献 4832) 常见于盐分较低的红树林沼泽与在较少污染的运河中。 时常见到伴随着 Aplocheilus. 吃昆虫。
