them clown loaches are not gonna make it. they may even harm the gatf with the blades. i watch mine bite goldfish in half then eat them. yours at the size could bite one of the loaches from the side with ease. they can get the top jaw on the back and bottom jaw on the belly....it is all down hill for the loach from there. we'll see if you keep them in there long enough.
i am worried about putting 3" frontosas with mine....
