You cannot say they are fine just because they are always out and chasing each other. This shows me very clearly you do not understand their behavior.
Loaches like Histrionica, Rostrata, Almorhae, and Clown Loaches all share something very in common (Yoyos are Almorhae). They are highly social species of fish. This does not mean that they can be social. It means that the need to be social, as this is part of their nature.
The "Chasing each other around" is a behavior they do because they establish something called a social hierarchy. It is common to see them challenge each other in the form of chasing, posturing, spinning in circles, and fading their colors to gray. At first this behavior is harmless and innocent. In a proper shoal size no one fish is being picked on too much. Even when a fish knows it is in charge, it will still chase and challenge other fish as if to ensure they know who is in charge.
My Yoyo shoal has one big fat one in particular who is constantly in struggle with a second slightly smaller yoyo. They often pick on each other over dominance but usually the fat one wins. Then he turns around and chases the other Yoyos, and the smaller Rostata and Histrionica as well.
I have seen the smaller of those two Yoyo attempt to go up against the two big Histrionica and they promptly put him in his place! I've seen those two big things push the little young Histrionica around even though they are a fraction of their size and hardly able to put up competition.
From what I can see the yoyo are not the same in behavior when compared to the Kuhlis. I have seen videos where people keep a few yoyos with Kuhlis and the behavior of the yoyo are not desirable. The either hide and refuse to come out, or are gigantic bullies to everything in the tank.
You want to keep fish, you need to keep them in proper conditions and groups. Save yourself a big headache and make those animals happy. Either find them someone who will give the a proper size group (or take them back to the store) or bring home 3 more yoyo's to give them a proper shoal.
