This fascinating loach is very peaceful, has a very active and outgoing personality, and is very hardy in a mature aquarium with rich algae/biofilm and very high water flow. The Spotted Borneo Sucker (Gastromyzon punctulatus) is a very interesting freshwater loach that is native to Malaysian Borneo. It is known for its grey body colouration, white spots, and occasional blue highlights on its fins, its peaceful yet outgoing demeanour, and its fascinating social behaviour with members of its own species. This fascinating, peaceful fish is an algae and biofilm grazer that is an excellent candidate for the mature subtropical aquarium. An aquarium with heavy water flow (10-15x turnover per hour) and very clean, clear water is required for the Spotted Borneo Sucker. Like other hillstream loaches, this loach is native to shallow, clear, fast-flowing waters and it is sensitive to declines in water quality, so regular aquarium maintenance and maximum oxygen saturation are absolutely necessary. It is known to usually accept frozen meaty foods, but such foods should only be fed occasionally since excess protein can be deadly to most biofilm grazers. This fish will also often accept high-quality dry foods that are rich in plant matter, but it is absolutely essential that biofilm and algae are naturally available in the aquarium to ensure its long-term health or else it may slowly starve. As long as it is kept in a well-maintained, mature aquarium with good biofilm and algae growth as well as high water flow, the Spotted Borneo Sucker is a hardy and entertaining fish. It will not bother aquarium plants. The Spotted Borneo Sucker is a very social species, especially as an adult, so it should be kept in groups. Most small rasboras, tetras, hillstream loaches, gobies, and other small, peaceful fish are good tankmates for this species. Since they inhabit similar waterways, many smaller freshwater goby species are ideal tankmates as well. Due to its small size and diet, the Borneo Sucker can also be kept with dwarf shrimp, although it might eat a few of their fry. Peaceful bottom-dwelling fish are also a possibility, but care must be taken to make sure that the Borneo Sucker is not outcompeted for food. Little reliable information is known about the breeding habits of the Borneo Sucker. However, it is not necessarily unlikely that it will soon be bred in the aquarium world, especially with the recent progress in breeding other loach species by many individuals. What We Like About This Fish: Extraordinary-looking with its highly unique, hydrodynamic shape and beautiful pattern Peaceful disposition with fish and peaceful invertebrates Interesting, active social behaviour when kept in colonies Long lifespan when kept in optimal conditions Safe with dwarf shrimp RECOMMENDED TANK PARAMETERS: Temperature: 68° - 75° F (20° - 24° C). Higher temperatures can be tolerated temporarily with extremely high oxygen content.. pH: 6.0 – 7.5 KH: 4 - 8 dKH Minimum Tank Size: 20+ gallons for a small group. CARE INFORMATION: Diet: Omnivorous. Typically accepts some dry foods and frozen foods, but requires ample algae and biofilm for longevity. A diet too high in protein can cause serious health problems or even death in this species. Social Behaviour: Peaceful. Juveniles sometimes appear solitary, but adults exhibit schooling behaviour. Origin: Borneo, Malaysia Average Adult Size: 1.4 – 1.6 inches (3.5 - 4 cm) Average Purchase Size: 1 - 1.5 inches (2.5 - 3.8 cm)
