概述
L264（Leporacanthicus joselimai）来自塔帕若斯河，是需要富氧流水的异型。幼鱼醒目的白色鳍尖会随生长褪淡甚至消失，不能把这种正常变化直接当作健康恶化。
分布与栖息地
分布于巴西塔帕若斯河，生活在急流和其他流速较快的河段，利用岩石、沉木缠结处躲藏。
饲养环境
提供宽敞空间，优先铺沙，使用较大沉木和光滑石块制造洞隙、阴影。较暗照明有益，水中需有高溶氧和适当流动，可按需要增加造流或气石。
排泄量较多，过滤系统要有效，不能只满足水流而忽略水质。
食性与喂食
偏好动物性食物，可喂红虫、切碎贻贝、虾肉等活饵或冷冻饵，搭配沉底干粮。藻和植物性物质通常不常吃，偶尔可能啃黄瓜或西葫芦，不宜把蔬菜当作主要菜单。
习性与混养
可考虑环境相容的脂鲤、温和慈鲷和适合的小型鲶鱼。水流很强的布置会缩小可选伙伴范围，需要逐一核对适应性。
对同种有领地意识，雄鱼之间尤其明显。想养多条时，应准备足够空间和多处分隔的潜在领域，不能只增加一两个洞口。
雌雄区分
成熟雄鱼头更长、更宽，背鳍较大，齿突更多；从上方观察通常更容易比较。
繁殖
人工繁殖已经实现，属于洞穴产卵，但详细过程有限。不能把其他属的成熟繁殖流程当作本种已验证步骤。
补充说明
上颌两枚较大的牙齿是 vampire 商品名的来源，可能用于抓取螺等无脊椎动物，具体作用尚不明确。头顶小骨质突起的功能也未确定。
白色鳍尖在幼年更明显，长大后可能完全消失。购入时更应关注腹部是否饱满、眼睛是否凹陷，而不是只追求幼鱼的鳍色。

Overview
The L264 pleco, Leporacanthicus joselimai, needs oxygen-rich moving water. Its striking juvenile white fin tips fade with growth and may disappear completely, a change that should not automatically be interpreted as declining health.
Distribution & habitat
It comes from Brazil's Tapajós River, using rocks and tangled wood in rapids and other fast-flowing reaches.
Aquarium setup
Provide spacious quarters with sand, substantial wood, and smooth stones forming shaded crevices. Subdued lighting is useful. Maintain high dissolved oxygen and movement, adding circulation or aeration as required.
Waste production is considerable, so effective filtration and water maintenance are essential alongside flow.
Diet & feeding
Animal foods are preferred: live or frozen bloodworms, chopped mussels, and shrimp flesh can accompany sinking preparations. Algae and other plant material are taken less often, though cucumber or zucchini may occasionally be nibbled. Vegetables should not become the main ration.
Behaviour & compatibility
Suitable characins, peaceful cichlids, and appropriate smaller catfishes are possible companions. Strongly flowing aquaria narrow those choices, making individual assessment important.
Territoriality toward conspecifics is especially marked between males. Groups require sufficient space and several separated potential territories, not simply another cave entrance in crowded quarters.
Sexual dimorphism
Mature males have longer, wider heads, larger dorsal fins, and more extensive odontodes. Comparing fish from above is useful.
Breeding
Captive reproduction has occurred, and it is a cave spawner. Detailed methods are limited, so established routines for another genus should not be presented as verified for this fish.
Notes
The enlarged upper-jaw teeth explain vampire trade names. They may help grip snails or other invertebrates, but their exact function remains unclear, as does the small bony projection on the head.
White fin tips are strongest in juveniles and can vanish in adults. When selecting fish, abdominal fullness and the absence of sunken eyes matter more than retaining juvenile fin color.
