Kuhlis are avid diggers and enjoy burrowing and burying themselves in the substrate. This makes fine sand ideal, but other, coarser types, like pool filter sand (diatomaceous earth) are also fine. Avoid sharp, pointy gravel as this can easily damage their sensitive barbels. Round river rock or small rounded gravel is fine, but sand would still be the best of all. Email me if you have any questions.
it somewhat is how we've continuously performed it. Take a wood chopstick or a barbeque skewer and push it into the gravel against the glass the place you will locate it. This guarantees you will no longer stab the fish. Then slowly drag the stick via the gravel going lower back and forth from the front to the lower back of the aquarium. The transferring gravel will reason the loach to return out of hiding previously the stick somewhat touches it. as quickly as he's out in the open you are able to siphon your gravel without hardship.
I actually had a kuhli loach for 4 years just with the regular gravel you can buy in bags, and it was fine until my kids decided to put candy's in my tank and killed all my fish in there :(
You will want something very light so that they can burrow into it. If you don't like any form of sand then perhaps the crushed coral that people use for marine aquariums would be best. I would strongly recommend the sand as this will be the easiest on them and keep them from being stressed.
