Advice! New Betta & Tankmate!

So I just recently got a half-moon double-tail Betta. He's very pretty and I really like him. He is also my first fish. He's a very chill calm fish, I suppose. He doesn't move around a whole lot when I'm around. He likes to hide behind plants or the filter. Yesterday I got him a tankmate! I purchased a Dojo Loach to put in there with him. I'm not sure if this is normal or what this means, but my betta likes to sit on him? Like they're literally behind a plant and my betta just has popped a squat right ontop of him. I haven't seen any aggressive behavior towards him to my Dojo, actually this is the only contact I've seen from both of them. Last night I definitely noticed a change in my Betta, he has gotten more active, he would swim around I guess searching for his new friend? Once he found him and decided to chill out he would just lower himself ontop of him. My dojo isn't any fancy color, he's just a white one. Has anybody else tanked a Betta with a dojo? How did that turn out?

Hmmm..... I looked up the dojo loach, and the websites said that they need a large tank, one said at least 30 gallons and the other said at least 55 gallons. Also, all websites said that they need cooler water than most tropical fish, in the 65 to 75 degree range. Your betta being on top of him might be an act of aggression.
Is this what you mean by a 'dojo loach'?

If it is, it looks like BettaBeau is correct in its unsuitability as a tank mate for a Betta splendens.

You have to remember Betta splendens are a solitary fish. The increase in activity levels in your fish could be because he (rightly) believes that the loach has intruded on his territory.

Bettas don't need to be physically attacking a fish to be behaving in an aggressive manner towards it. Often aggressive behaviour can be very subtle, and I'm not so sure that the betta resting on top of the loach is necessarily a benign behaviour. It seems rather an intimidating/threatening gesture to me.
