Rosy Loach

A tiny rosy-orange loach with a slender body, translucent fins, and fine darker markings that are strongest in settled adults.

The aquarium fish remains unidentified to species. Tuberoschistura arakanensis is a misapplied trade name and should not be used as an accepted identity.

Sexes are difficult to distinguish reliably outside breeding condition. Mature females may become fuller through the abdomen, while males of some species develop stronger colour, fin shape, or breeding tubercles.

Set up a mature aquarium at least 45 cm long with clean, well-oxygenated water, smooth gravel and sand, rounded rock piles, crevices, and a secure lid. Arrange several separate shelters and keep detritus from collecting beneath hardscape.

Rosy Loach is a bottom-dwelling stream loach that searches among stones and crevices for small prey. It may rest in cover, then move quickly into current or across the substrate when feeding.

Keep 6 to 10 where the species is peaceful and space permits. For more territorial forms, a single fish or carefully observed group in a larger footprint is safer.

Adults may defend caves, rock gaps, or feeding areas from similar-shaped fish. Provide broken sight lines and multiple retreats.

Choose peaceful or moderately active stream fish that share the same temperature and oxygen needs. Avoid tiny shrimp, slow bottom fish, and combining several territorial loaches in a small footprint.

Maintain stable, clean water within the stated range. Oxygenation, low organic waste, and gradual acclimation are more important than forcing an exact pH or hardness value.

Offer small sinking foods rich in aquatic invertebrate protein. Combine a dependable prepared staple with frozen or live insect larvae, Artemia, Daphnia, or similar foods.

Feed small portions at more than one point because territorial fish may guard food in a confined area.

Reliable captive breeding information for Rosy Loach is unavailable because the trade form has not been identified to species. Do not transfer breeding claims from a visually similar species without evidence. A specialist trial would require mature conditioned adults, stable seasonal cues, and protected gravel or vegetation for any eggs.
