概述
宽头拟腹吸鳅（Pseudogastromyzon laticeps）来自广东海丰一带山溪。照顾这种贴附石面的鱼，需要把高溶氧、成熟生物膜和足够觅食面一并准备好；只有强水流而没有食物表面并不够。
分布与栖息地
模式地点在广东海丰莲花山，可能仅分布于流经海丰的龙江水系。栖息浅而富氧的上游急滩，石砾和大卵石间有水潭，岸边植物及落叶较常见，水草少。季风强降雨可能暂时让溪流变急、变浑。
饲养环境
底面积至少参考 75 × 30 厘米。砂砾上铺大小圆石，成熟沉木、附生植物和外露海绵可增加觅食与遮蔽面。过滤循环宜超过每小时十倍水体，按需增氧，但不必制造激流。较强灯光培养生物膜，避免新沉木大量染水；定期部分换水，勿一次清掉全部附着物，缸盖要贴合。
食性与喂食
同属主要刮食蓝细菌、硅藻及少量微小无脊椎动物，长丝藻和牢固附着的硬藻未必大量摄食。可辅以下沉干粮及定期活冷冻饵，藻膜不足时另缸培育长藻石轮换。瘦弱个体应减少竞争，持续供给适口食物。
习性与混养
野外呈松散聚集，建议六尾以上。参考同属经验，相似体形的鱼可能引发争执，较小、较弱的吸鳅尤其需要谨慎；也不适合与金鱼搭配。雄鱼可能较大胆并占据觅食小区，但本种实际强度仍需观察。
雌雄区分
成熟雌鱼较大丰满，体纹反差通常较弱；雄鱼头部会长珠星，优势雄鱼更明显。
繁殖
可借鉴麦氏拟腹吸鳅（Pseudogastromyzon myersi）的方法尝试，但不能当作本种已确认的繁殖流程：用成熟圆砾底和长藻石，海绵过滤保护卵与鱼苗。近亲雄鱼会在石旁挖坑，雌鱼入坑分批产卵，受精后雄鱼覆砂，此后不继续护幼。鱼苗在砾缝内发育，出来后即开始刮食。

Overview
A stream loach from the Haifeng area of Guangdong, Pseudogastromyzon laticeps needs established rocky feeding surfaces as well as clean oxygenated water. Aquarium preparation should develop both biological stability and usable biofilm before fish arrive.
Distribution & habitat
The type locality is a stream on Lianhua Mountain, and the species appears restricted to the Longjin drainage. Shallow oxygen-rich channels have rocky riffles interspersed with pools, riparian vegetation, and leaf deposits. Monsoon rainfall can temporarily increase flow and suspended sediment.
Aquarium setup
Provide at least a 75 by 30 cm footprint with rounded stones over sand or gravel. Established wood, hardy plants, and accessible sponge add shelter and feeding surfaces. Suggested turnover exceeds ten tank volumes per hour, with extra aeration if needed; a torrent is unnecessary. Strong light promotes biofilm. Avoid heavily staining new wood, retain growth during partial water changes, and secure the lid.
Diet & feeding
Genus-level accounts emphasize cyanobacteria, diatoms, and some minute invertebrates rather than heavy consumption of long or tough algae. Offer regular small live or frozen foods alongside accepted prepared diets. Rotate cultured grazing rocks when growth runs short, and provide weakened fish with food away from competitors.
Behaviour & compatibility
Six or more reflect its loose natural aggregations. Experience with congeners suggests possible disputes with similarly shaped fish, especially smaller or less assertive loaches, and goldfish are unsuitable companions. Males may be bolder and establish feeding territories, but the degree of territoriality remains uncertain.
Sexual dimorphism
Mature females are larger, fuller, and usually less strongly patterned. Males develop head tubercles, especially when dominant.
Breeding
A trial can draw on breeding methods used for Pseudogastromyzon myersi, without treating them as established for this species. Mature rounded gravel, algal rocks, and sponge filtration provide the basic setting. In that relative, males excavate beside rocks, females deposit successive egg batches, and males fertilize and cover them. Further parental care stops; young develop within gravel and graze on emergence.
