概述
L333 是巴西辛古河下游的未描述 Hypancistrus，浅色花纹可以从白色、黄色到锈橙色，个体变化很大。它常与其他编号混淆，不能只按白色浓淡或售价判断身份。
分布与栖息地
仅知来自巴西北部帕拉州 Porto de Moz 附近的辛古河下游。水电开发是该流域水生环境曾被指出的压力之一，但具体工程状态不能由旧记录直接判断。
饲养环境
采用溪流式布置，以石块、圆石、沙和细砾组合底床，再用沉木、陶管、花盆形成洞隙、阴影和视线遮挡。
保持洁净水质，每周约 30%～50% 换水。需要高溶氧和适当水流，重点是充分供氧，不必把整缸做成无法停留的湍流。可根据需要增加过滤、造流泵或气石。
食性与喂食
天然可能杂食而偏好水生无脊椎动物。缸中应把沉底干粮与冷冻水蚤、孑孓、红虫、虾肉等搭配，生马铃薯和其他蔬菜也可能被接受。
自制凝胶饵能同时加入鲜蔬菜、螺旋藻与肉类成分，便于维持多样食谱。
习性与混养
总体温和，可与安静、环境需求相近的伙伴共同饲养，避免强领地或好斗鱼类抢占资源。为防杂交，不应与其他 Hypancistrus 混养繁殖。
雌雄区分
成年雄鱼头较宽，胸鳍前缘及鳃盖附近齿突更发达，老雄可能颜色更深。俯视时雄鱼较纤细，雌鱼较厚实。
繁殖
在洞穴中产卵，由雄鱼照护后代，人工繁殖已有多次成功。若藏身处足够，鱼苗可以留在成鱼缸里成长。
补充说明
与 L066 相比，L333 底色较深，浅色纹不那么细；与 L400 相比，体形较短壮。白色变异有时被误标为 L236 以抬高价格，因此编号需要额外核对。
市场还出现过白化个体，以及疑似选育或杂交型。对这些来源不能作未经确认的纯种保证，颜色本身不是可靠谱系记录。

Overview
L333 is an undescribed Hypancistrus from the lower Xingu. Pale markings range from white through yellow to rusty orange, and substantial individual variation creates opportunities for mislabeling. Whiteness or price alone does not establish identity.
Distribution & habitat
It is known from the lower Xingu near Porto de Moz in Pará, northern Brazil. Hydroelectric development has been identified as pressure on the basin's aquatic habitats, without establishing the current status of any particular project here.
Aquarium setup
Combine sand, fine gravel, and varied stones in a stream-style aquarium. Wood, ceramic pipes, and pots can create a network of shaded caves and broken sight lines.
Maintain very clean water with weekly changes of approximately 30–50%. High oxygen availability and some movement are important; torrent-like conditions throughout the aquarium are unnecessary. Supplement filtration with circulation or aeration as needed.
Diet & feeding
Wild fish are presumed omnivorous with a preference for aquatic invertebrates. Offer varied sinking foods, frozen water fleas, mosquito larvae, bloodworms, and shrimp flesh. Raw potato and other vegetables may also be taken.
Homemade gel foods allow fresh vegetables and Spirulina to be combined with animal ingredients.
Behaviour & compatibility
Generally peaceful, it can live with appropriate quiet companions. Avoid strongly territorial or aggressive competitors. Other Hypancistrus should not be mixed for breeding because of hybridization risk.
Sexual dimorphism
Males develop broader heads and stronger odontodes on the leading pectoral rays and near the gill covers. Older males may darken. From above, males are slimmer and females more heavily built.
Breeding
A cave spawner with male brood care, it has reproduced repeatedly in aquaria. With ample cover, fry can grow alongside the adults.
Notes
Compared with L066, L333 has a darker background and coarser pale markings. It is shorter and stockier than L400. White variants have sometimes been sold incorrectly as L236 at inflated prices, making independent identification useful.
Albino fish and apparently selected or hybrid forms have also entered the trade. Appearance alone cannot provide a reliable pedigree or confirm the origin of these variants.
