Not much to give you, I'm afraid.
High probability that it is an internal bacterial infection, however even strong antibiotics are insufficient. Incubation time may exceed three weeks. Nearly 100% fatality rate. Immunity appears to be possible but quite rare. Spreads to other loaches and at least closely related non-loach cyprinids. Symptoms seem to be mostly secondary, the true symptoms are limited to drop in activity, which may be hard to realize. Erratic swimming reminiscent of SBD seems to be the symptom of the late stage disease. So really not much to look for, except as I wrote above: try to avoid fresh imports (cf. kuhlis) and quarantine, separately from other fish. At least a month is needed, perhaps more.
