Care
All too often, this species is sold for algae-eating purposes in the community aquarium. Sadly, it is usually only juvenile specimens which seem to exhibit this trait - adults becoming less interested in algae eating and more interested in terrorising the other occupants of the tank. Slow-moving fish will become the focus of this species attention, where it often latches on and causes damage with its sucking-disc. These Sucking "Loaches", which are in fact not actually a real loach species, usually come with a temptingly low price tag; however, there are far better options to choose from if an algae-eating fish species is desired: e.g. Bristlenose catfish, Clown plecostomus, Amano shrimp, Garra sp., Siamese Flying Fox (Crossocheilus siamensis) etc. When maintaining Sucking "Loaches", a spacious aquarium should be provided due to the eventual large adult size of this species. In the wild, its sucking-disc allows it to keep position in fast streams and rivers whilst feeding on the algae for the micro-organisms it contains, at the same time taking on water for gas exchange through spiracles located at the top of the gill covers. As these fish inhabit flowing waters, a corresponding fast flow rate and smooth rockwork/cobbles are much appreciated in the aquarium. Tankmates should be robust and fast-swimming. Adults can be very territorial when housed together (or when housed with similar-looking fish), so ensure enough space and hiding places are provided. To minimise interspecific aggression, keep individually or else in a large group; low numbers (e.g. 2 or 3 specimens) can result in certain individuals becoming constantly harassed. Plant cover will be appreciated, although again, opt for the hardier species, as these fish will destroy delicate and softer leaved vegetation. Golden and marbled varieties of this species are also available. May also be seen on sale as Chinese Algae Eater. Sucking "Loaches" "“ think before you buy!
