Not sure ,you have pics ? A pic may help. Keep in mind clown loaches are scaleless fish and as such are more susceptible to poor water quality and disease. Also keep in mind they are a shoaling fish that belong in groups of at least six and can get up to a foot each so having a group of at least 6 would require at minimum 75 gallons ideally more.

Video would be more instructive than even photos, if there are swimming issues. Utahfish is correct, this is a shoaling species that must have a group. It is also a highly social fish (loaches in general are), establishing an hierarchy with an alpha fish (usually a female) that literally runs the show. They get large, 8-12 inches, and need at least a 6-foot tank but 8-feet is preferable. Before acquiring any more, keep this in mind.
