The infestation is usually controlled by chemicals, such as praziquantel (Schmahl and Mehlhorn,
1985; Stetter et al., 2003), mebendazole (Buchmann et al., 1995), quinaldine (Crigel et al., 1995) and
toltrazuril (Schmahl and Mehlhorn, 1988). In China, praziquantel and mebendazole are commonly used.
国外常用的治疗指环虫的化学药物有：吡喹酮，甲苯咪唑，喹哪啶，甲苯三嗪酮；我国常用的是吡喹酮，甲苯咪唑。
Cumulative doses up to 10 mg praziquantel/l water were tolerated without side-effects by Angel Fish (Pterophyllum scalare), Discus, and a variety of catfish species (Ancistrus sp., Corydoras sp.). It was found appropriate to start with a dosage of 2.5 mg/l and to add the same dosage every other day several times. All adult parasites and larvae were killed by this treatment. For the complete elimination of the Dactylogyridae-population in a closed aquarium system, 3 therapy-cycles (duration: 5-6 d, accumulated dosage: 2.5 mg/l/d) prooved to be effective. It was important to interrupt the therapy-cycles with intervals without medication (1 to 4 weeks).
在不换水的养殖系统中，吡喹酮浸泡，浓度2.5g/立方米，隔一天用一次，连续使用3次可以杀灭所有的指环虫。
不过别人是针对热带观赏鱼，此方法仅供参考。
