概述
L114 是带暂定鉴定的 Pseudacanthicus 异型鱼，贸易中也称 LDA007。它需要很大的河流式水族箱和充分遮蔽；学名中的近似标记意味着身份尚未完全确认，不宜省略后当成确定命名种出售。
分布与栖息地
主要采自巴西亚马孙州内格罗河，尤其巴塞洛斯地区汇入内格罗河中段的德米尼河。被用来比较的命名种来自圭亚那另一水系，正是身份尚待厘清的原因。
饲养环境
长期饲养应考虑缸长至少 180 cm 的大底面积。用不同大小的石块、砂、细砾和水磨巨石模拟河流，配沉木枝条、陶管或花盆，组成多处阴影与缝隙，并切断直线视野。
食性与喂食
天然可能杂食而偏向水生无脊椎动物。缸中搭配沉底干粮、冷冻水蚤、蚊幼虫、红虫与虾肉，也提供少量新鲜果蔬或煮软的薯类。自制凝胶饵可把植物、藻类及动物性原料混合，菜单保持多样。
雌雄区分
成年雄鱼头更宽，齿状突起更发达，胸鳍前缘及鳃盖下方区域尤其明显。
繁殖
已有人工繁殖，在洞中产卵，由雄鱼照料后代。

Overview
Traded as L114 or LDA007, Pseudacanthicus cf. leopardus retains a provisional identification. It needs a large river-style aquarium with substantial shelter. The tentative qualifier is meaningful and should not be silently dropped from its identity.
Distribution & habitat
Collections mainly come from the Negro basin in Amazonas, especially the Demini entering the central Negro near Barcelos. The named species used for comparison was described from another drainage in Guyana, leaving the identity of this trade fish unresolved.
Aquarium setup
Long-term housing requires a large footprint at least 180 cm long. Combine mixed rocks, sand, fine gravel, and worn boulders in a river-style layout. Branches, ceramic tubes, or pots create shaded retreats and interrupt direct sight lines.
Diet & feeding
It is probably omnivorous in nature with a preference for aquatic invertebrates. Offer varied sinking prepared foods, frozen water fleas, insect larvae, and shrimp, alongside some fruit or softened vegetables. Gel-bound homemade foods can combine vegetables, spirulina, and animal ingredients.
Sexual dimorphism
Adult males develop broader heads and more extensive odontodes, particularly along the leading pectoral rays and around the interopercular region.
Breeding
Captive breeding is established through cave spawning, with the male caring for the brood.
