概述
L006（Peckoltia oligospila）是一种体侧斑点、鞍斑较淡的异型，总体相对温和，却会对同种及相近体形鱼守地盘。溪流式布置、多洞隙和视线遮挡比单纯追求开阔裸底更适合它。
分布与栖息地
分布于巴西托坎廷斯州、帕拉州的托坎廷斯河与 Capim 河及部分支流。模式产地旧拼作 Capin，可能对应 Capim 河。
饲养环境
用不同大小岩石、沙、细砾和圆石组成底床，以沉木、陶管或花盆构成相连但互有遮挡的藏身处，提供阴影和可分开的空间。
食性与喂食
天然可能杂食而偏好水生无脊椎动物。缸中可将沉底干粮与冷冻水蚤、孑孓、红虫、虾肉搭配，再补充鲜果、稍煮熟的马铃薯。
自制凝胶饵可同时加入鲜蔬菜、螺旋藻与动物性材料，维持多样食谱，不把它当作只吃藻或只啃木的鱼。
习性与混养
一般相对温和，但与同种及体形类似者存在领地竞争。多鱼同缸应让每条鱼能占用相对独立的藏身空间。
雌雄区分
成年雄鱼尾柄和鳃盖有发达齿突，身体比雌鱼更纤细，俯视较容易观察差别。
繁殖
洞穴产卵，由雄鱼照顾卵与幼鱼。
补充说明
与 Peckoltia bachi 相比，本种腹鳍棘较窄，眼睛位置较高，体斑为较分离的圆点而非斑驳状。较大幼鱼和成鱼腹部有斑，尾鳍斑点彼此分离，也有助于与 Peckoltia furcata 区分。
个体斑纹较淡，鉴定应同时看体形、鳍斑和腹部，不能只根据浅色或深色程度决定编号。

Overview
L006, Peckoltia oligospila, has relatively faint body spots and saddles. Its generally peaceful behavior includes territorial competition with conspecifics and similarly shaped fishes. A stream-style aquarium with sheltered, visually separated spaces suits it better than an exposed floor.
Distribution & habitat
It is recorded from the Tocantins and Capim systems and some tributaries in Brazil's Tocantins and Pará states. The historical type-locality spelling Capin appears to refer to the Capim.
Aquarium setup
Combine differently sized rocks, sand, fine gravel, and rounded stones. Wood, ceramic tubes, or pots can create shaded refuges with interrupted sight lines and separately usable spaces.
Diet & feeding
Wild fish are presumed omnivorous with a preference for aquatic invertebrates. In captivity, vary sinking preparations with frozen water fleas, mosquito larvae, bloodworms, shrimp flesh, fresh fruit, and parboiled potato.
Gel foods can combine fresh vegetables and Spirulina with animal ingredients. It should not be assumed to live exclusively on algae or wood.
Behaviour & compatibility
Overall behavior is relatively peaceful, but conspecifics and similar-looking fishes can compete for territory. Multiple occupants need refuges that can be used independently.
Sexual dimorphism
Males develop odontodes on the caudal peduncle and opercle. Mature males are also slimmer than females, a difference most easily compared from above.
Breeding
It spawns in caves, with the male tending the brood.
Notes
Compared with Peckoltia bachi, this fish has narrower pelvic spines, higher-set eyes, and distinct rounded spots rather than mottling. Spots on the abdomen of larger juveniles and adults, together with separate caudal spots, also help distinguish it from Peckoltia furcata.
Because markings can be faint, use body shape, fin patterns, and the abdomen together rather than identifying a code solely by color intensity.
