概述
Chaetostoma sp. L187a 是身份未确定的斑点型异型，来自凉爽富氧的山溪。它对水流和含氧条件有专门要求，多尾同养还必须分配各自的石块藏处。
分布与栖息地
来自哥伦比亚的快速山溪，底部为岩石，水通常清澈、偏凉，溶解矿物较多。
饲养环境
一对可用约 75 × 30 × 30 cm 的缸，组群更大。砂底配大量平滑卵石与不同大小岩块，造流设备提供持续水流和增氧。温度过高或溶氧不足时难以养好。
多数水草在这种条件下表现不佳，结实的附生植物可尝试，但不要以草缸布景为首要目标。购入新鱼时检查腹部是否饱满、眼睛是否下陷，避免忽略严重消瘦。
食性与喂食
杂食。提供焯菠菜、西葫芦、黄瓜片等植物食物，搭配红虫、丰年虾等活饵或冷冻饵，也能吃藻片及其他干粮。
习性与混养
对其他鱼较友善，但伙伴必须适应凉爽富氧和水流。对同种有领地意识；空间与布景合适、每尾都能占有一块石头时，通常可养数尾。
雌雄区分
雄鱼一般较修长，成熟后头部明显更宽，胸鳍也更大。
繁殖
本记录没有确认的人工繁殖。近缘 L187b 的经验可供尝试参考：雄鱼占石下洞穴，必要时挖洞，守护洞内卵；约 7～10 天孵化，幼鱼再过 2～3 天开始积极觅食，需要持续适口食物及每日小量换水。以上时程并非 L187a 的已确认记录。
也有用约 50%～70% 稍凉换水模拟雨季的建议，间隔数日重复仅是尝试方向，降温需留在适宜范围，不保证产卵。
补充说明
L187、L187a 与 L187b 不应只按编号相近就当作同一种，贸易误认存在。保留具体标签与来源，避免把另一编号的繁殖记录混入本条。

Overview
The unresolved Chaetostoma sp. L187a is a spotted pleco from cool, oxygen-rich mountain streams. Specialized flow requirements and territoriality between conspecifics demand more planning than its generally amicable behavior might suggest.
Distribution & habitat
It comes from Colombia, inhabiting fast mountain waters over rock. Streams are typically clear and cool, with relatively high dissolved mineral content.
Aquarium setup
A pair can use an aquarium around 75 × 30 × 30 cm, with larger quarters for a group. Sand, smooth pebbles, and rocks of varied sizes provide individual shelters. Flow equipment should maintain movement and oxygenation. Excessive warmth or low oxygen makes the setting unsuitable.
Many plants struggle in these conditions, although hardy attached types may be tried. Check new fish for a full abdomen and nonsunken eyes; severe emaciation should not be overlooked.
Diet & feeding
It is omnivorous. Combine plant foods such as blanched spinach, zucchini, and cucumber with live or frozen bloodworms and brine shrimp. Algae wafers and other dry foods are also accepted.
Behaviour & compatibility
Generally friendly toward other fishes, it still needs companions compatible with cool, oxygenated moving water. Conspecifics compete for territory. Several can usually coexist if space and layout allow each its own rock retreat.
Sexual dimorphism
Males tend to be slimmer and develop much broader heads and larger pectoral fins at maturity.
Breeding
Confirmed aquarium reproduction is unavailable for L187a. Experience with related L187b suggests a possible approach: males defend rock caves, sometimes excavating them, and guard eggs. Reported hatching takes seven to ten days, with active feeding another two or three days later. Continuous suitable food and small daily water changes support those fry. These timings are comparative guidance, not verified L187a results.
Changes of roughly 50–70% with slightly cooler water every few days have been suggested as a stimulus. Stay within appropriate temperatures and treat this as an attempt rather than a guaranteed trigger.
Notes
Similar codes do not establish identical species. Keep L187, L187a, and L187b records distinct, particularly when documenting reproduction.
