Every boarding service has a routine built on rounds: look in the tank, see the fish, feed the fish, move on. Kuhli loaches defeat that routine completely, because a well-housed kuhli is an invisible one, buried in substrate or threaded through cover, active only when the lights are off. Whether a service knows this species is therefore not a question of trivia. It is a question of whether their whole way of working has room for an animal they cannot see, and your interview should probe exactly that.
Ask what the loaches will burrow into
Kuhli loaches rest half-buried and push through the top layer of the tank floor, and they are scaleless, soft-bellied fish that sharp gravel can injure. Ask what substrate the boarding tanks use, and treat sand or fine, smooth gravel as the only acceptable answers. A service that boards bottom fish on coarse stone, or in bare tanks for easy cleaning, is optimizing for its staff rather than its guests. Follow with cover: each tank should hold caves, tubes, wood, or dense planting, because a kuhli without a hiding place spends the stay stressed and exposed. Staff who keep the species often mention leaf litter or coconut caves unprompted, which is a good sign.
Ask about the lids, in detail
Kuhli loaches are among the great escape artists of the hobby, capable of leaving through filter slots and cable gaps that defeat other fish. Ask the service directly whether its boarding tanks are fully covered, and then ask the follow-up that reveals experience: have they ever found a loach in a filter? Keepers who know kuhlis laugh at that question because it has happened to everyone who keeps them, and they have since sponged their intakes and sealed their gaps. A blank look, or an assurance that fish do not really escape, tells you your loaches would be the facility's first lesson.
Ask when the bottom gets fed
Boarding rounds usually run in the morning, and a kuhli tank fed on that schedule is a tank where the loaches eat nothing while the water absorbs sinking food all day. A service that knows the species feeds bottom dwellers last, at lights-out, dropping small sinking foods close to the cover where the loaches shelter. Ask who does the evening feed and what the food is. Micro-pellets and small wafers named confidently, with amounts kept modest because uneaten food in a burrowed substrate is hard to retrieve, mark out staff who have actually run a tank of these fish rather than read about them.
Ask how they check on fish they cannot see
This is the question that separates keepers from custodians. Digging through decor to count loaches is stressful for the fish and pointless as a routine, so a knowledgeable service monitors indirectly: food placed at a known spot in the evening is gone by morning, the substrate shows fresh furrows, and the tank's water stays clean and normal. Ask what would make them investigate further, and listen for patience with a plan, such as a torch-lit look after dark when the loaches emerge, rather than a midday excavation. A service comfortable saying we mostly leave them alone, and here is how we know they are thriving, understands the species deeply.
Ask the intake question last
Finish by asking whether the service has boarded kuhli loaches before, and how many it holds at once. Small numbers, honestly admitted, with the housing and feeding answers above, beat breezy claims of handling everything. These fish also travel poorly in bags left waiting, so ask whether intake is a booked slot with the tank ready, which matters for a species that should go from transport water into quiet cover quickly.
