Do loaches build caves?

[Ded1]

Just wondering...how and do you, clean the favourite hiding places of your loaches?
Lets say that place is under a driftwood, like in mine case. Do you guys "destroy" it and clean with a gravel cleaning tube and than put it back etc...?

I believe that is the only way, but it is kind a stress for a fishes I presume.

every so often i have to pickup my tank ornament out of the loach tank and clean it in the sink. the loaches take their hikari wafers and eat them in their favorite spot. often times food debris gets stuck in hard to reach places.
