Pair of fish swimming in tight circles

[Pandy]

Hi guys,

I have noticed recently that a pair of my Celestial Pearl Danios often swim in tight circles with each other, nose to tail, for a good couple of minutes at a time. I have had a search on here but couldn't really see if anyone had experienced the same as I guess it may differ between species.

Anyone got any thoughts on what it may be?

I'm not sure if it's linked but I have lost two of my CPDs this month (3 weeks apart mind) but having kept a close on my water parameters I can't put it down to that as it has been spot on.

That's

it may be pairing of mating pairs?

im not sure at all but this is all i could think of

That was my first thought but I have no idea. If I have read correctly the males have deeper colourings and markings as opposed to the less prominent females, and the pair are one of each so it could well be that

Sounds like they are just flaring, I have a video of some of mine doing it, I think it's a dominance thing.

That's exactly it, thanks for posting that video

Yep mine do it too, it's fun to watch although I don't think the fish are amused lol Have you seen yours spawning yet? The male and female get into a tight "hug," very interesting.

Pretty cool stuff because I stumbled upon that fish while surfing earlier. Will try to find the link again but the author said suggested that 20? was a good # to have. Whatever the case I see a tank filled with those in my future. very pretty fish. and the sparring just gives them more personality.
