Yo-yo loaches and clown loaches

I have a Yo Yo and a Clown loach in a 190 litre tank, both about 5cm. They have been together for just over a year now with no particular problems. The Yo Yo often chases the clown loach around but doesn't seem to do anything other than chase. I have plenty of hiding places so the clown can get away if he wants.
 
You'll need to keep no less than 3 for each loach species. They should never be deprived of the company of their own members.

I've always heard that so I got 3 yoyo's and they pretty much hate each other. They seem very healthy and content, but they don't stay together. As a matter of fact, it seems like they avoid each other. :confused:

I really disagree with this notion of keeping 3 botia loaches, or that being the "minimum". I would consider a group of 5-7 to be far more appropriate.
