Can Anyone Identify This False Julii Cory Behaviour For Me?

HI guys,
This is my first post but I've used fishlore pretty extensively for problems of the past. This isn't a problematic post but I wanted to see if anyone could tell me about some cool/strange behaviour of two of my false JuliI cory. From my summations they are both male, so this could be some kind of territorial thing, and there are two other females in the tank (I'm basing this on body size and shape mind you, these could be female also). Anyhoo, these guys do this quite a lot, but the rest of the time school like normal and do normal cory things, digging in the sand, hiding in the plants, chasing a female etc. So they seem perfectly happy in each others presence, but then do this little dance, sometimes for about 10 minutes straight. Also I got a video of it but couldnt figure out how to add one to a post so yeah if there is a way to do that I can chuck those up so the behaviour is clearer.




Any ideas welcome Cheers!

Yeah, if they’re chasing and flailing their fins then it’s usually them “fighting” for dominance.

 

It's pretty fun to watch, they seem to try touch their dorsal fins while just staying in place. It's very polite as far as duelling goes haha.

 

It looks like it could be spawning behaviour, often the males will ‘dance’ in front of the females inviting them to spawn with them.
If you have a video of the behaviour that would show it more clearly, you have to upload it somewhere like YouTube first then post the link here.

Hahahaha just wanted to react like :
Looks like pre-spawning behaviour. Hormons in the males make them start swimming / playing together and then after some hours / days they'll start to chase a female and get in T-position.

There is no such thing as domination in Corys.

Let us PLEASE call them C.trilineatus.

 

Thanks everyone for the replies. The ladies must not be giving it up then because these dudes have been trying for months haha. I've read that I should do a water change with a lower temp by a couple degrees to initiate spawning, maybe I should give that a try. Here is a link to a video anyway:
