Two of my clown loaches appear to be fighting one another.

Does anyone here know what would cause clown loaches to fight one another?

They don't do it all the time, but these two are really going after one another night. I'd love to think they are kissing, but... they aren't I don't think.

this is something clown loaches do all day everyday, there is never any damage, they will chase each other nip and generally piss each other off. its fine and nothing to really worry about, I am not even sure its real fighting. when they are really fighting the colour turns almost white. A few of the other members with clowns have said pretty much the same of there loach.

they don't get stressed by it and as there is no damage no chance in infection

perfectly normal, Its part of CL's being CL's, they never injure each other
