It is currently traded as Gastromyzon sp., which means it has not yet been formally described to species level. In the aquarium it is a fascinating specialist fish for a river-style setup, where it will spend much of its time grazing across rocks, glass and décor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003eBloody Mary Borneo Loach.

Like other Gastromyzon, it is associated with fast-flowing, shallow, rocky streams with very high oxygen levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater Parameters:\u003c\/strong\u003e\u003cbr\u003eTemperature: 20–24°C\u003cbr\u003epH Range: 6.5–7.8\u003cbr\u003eHardness: soft to moderately hard water\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e\u003cbr\u003eGenerally peaceful and non-confrontational.

Best kept with small, calm fish that enjoy cooler, clean, highly oxygenated water, and ideally alongside other stream-type species that will not bully it. Watch out for boisterous community fish, aggressive bottom-dwellers, warm-water species and tanks with poor flow or low oxygen, as these are much bigger risks than aggression.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecial Requirements or Care Notes:\u003c\/strong\u003e\u003cbr\u003eThis fish needs a mature river-style aquarium with strong flow, excellent aeration, smooth rocks and stable water quality. It should not be added to very new or overly sterile tanks, as it benefits from algae and biofilm to graze on naturally. Good filtration and regular maintenance are essential.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e\u003cbr\u003eIntermediate fishkeepers\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e\u003cbr\u003eOccasional in trade\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAll images are a visual representation of the fish you will receive, made to be as accurate as possible.
