Betta rubra is an ornamental freshwater fish endemic to northern Sumatra, Indonesia. The B. rubra population has decreased in recent decades, and is classified as an endangered species in the IUCN Red List. This study aims to report for the first time infection by L. cyprinacea in B. rubra harvested from the Aceh Besar region of Indonesia. The fish samples were obtained from the Cot Bira tributaries, Aceh Besar District, Indonesia from January to December 2020. The results showed that the parasite infected 6 out of 499 samples in August and September, with a prevalence and intensity rate of 1% and 2 parasites/fish, respectively. The eyes and pectoral fins were the common infection sites. Despite B. rubra is not an optimal host (small size) for the parasite, this parasite might serve as additional threatening factors for the endangered B. rubra fish population.
霓虹刺盖鱼是印度尼西亚苏门答腊岛北部特有的一种观赏淡水鱼。近年来，霓虹刺盖鱼的数量减少，被列入 IUCN 红色名录的濒危物种。本研究旨在首次报告在印度尼西亚亚齐省大亚齐地区采集的霓虹刺盖鱼感染了鲤斜管虫。这些鱼样本于 2020 年 1 月至 12 月从印度尼西亚大亚齐区的科特比拉支流获得。结果表明，8 月和 9 月有 6 条 499 条样本受到寄生虫感染，感染率和感染强度分别为 1%和每条鱼 2 条寄生虫。眼睛和胸鳍是常见的感染部位。尽管霓虹刺盖鱼不是寄生虫的最佳宿主（体型小），但这种寄生虫可能成为濒危霓虹刺盖鱼种群的额外威胁因素。
