Address updates for a river-tank specialist
A hillstream loach move should notify the veterinarian, the aquatic shop, and any sitter or delivery arrangement of the new address and phone number, with a line added to each record identifying this fish as a cool, high-flow specialist. That description travels further than the species name, because a helper or advisor who pictures a standard still tropical tank will give standard advice that does not fit. Update deliveries of foods and filter parts to the new house, restate the tank's size and position on any landlord or household paperwork, and refresh the emergency sheet for the new room with the flow warning placed ahead of the feeding instructions.
Flow, oxygen, and temperature recorded as one system
A hillstream loach is built like a tiny suction cup for life in fast water, so its paperwork should describe current as a single system. Record the filter and any powerhead fitted in the rebuilt tank, the direction the flow runs, and where the strongest current crosses open rock, because that is where the loach will spend its grazing hours. Write the temperature the tank actually holds in its new room across a day, since a sunnier or warmer house can push a cool-water setup upward without any equipment failing. Note the surface agitation and spray arrangement too, because oxygen enters this tank through movement, and a helper who calms the surface has misunderstood the fish.
Rocks, algae surfaces, and the feeding record
A hillstream loach grazes biofilm and soft algae from stone, so the moving file should map the rebuilt rockwork: which smooth boulders sit in the flow, where the loach's favourite grazing face is, and which shaded stones it retreats behind. State plainly in the feeding notes that a spotless tank is not the goal for this fish, and list the supplementary foods offered, such as algae wafers and blanched vegetables, with their usual timing. A sitter briefed this way will not scrub the loach's pasture clean as a favour. Include a labelled photo of the rock layout, since flow and stone only make sense together.
The grazing rock rotation log
A hillstream loach file grows more useful if it keeps a simple rotation log for the rocks that feed the fish. Record which smooth stones sit in the brightest flow for building soft algae, and whether you ever rest a grazed stone in a sunny container of tank water to regrow its film before returning it. Note the loach's preferred stone after the move and any change in how long it grazes each day, because appetite measured against that log is an early report on the new setup. Few fish files reward this kind of detail, but a grazer's food supply is literally part of the furniture.
Power backup and local contacts at the new address
A hillstream loach depends on moving water more than most fish depend on a heater, so the updated paperwork should say exactly what happens at the new address when power fails: which battery air pump is stored where, and who the nearest backup is who can attend quickly. Name the shop near the new home that understands river tanks and stocks suitable foods and powerheads, refresh keyholders, and add sockets, fuse, and tap details for the new room. File the transport account, including how the loach was kept oxygenated on the journey. Keeping that flow-first record in KinsLe's Pet Passport gives the loach's next keeper the current facts in every sense.
