Harlequin Rasbora Mating Behaviour?

[stoneagedinosaur]

Morning all

A couple of my harlequins keep swimming in parallel with each other with dorsal fins raised. I think they are one male and one female but not 100%

What's the best conditions for breeding? Do they need anything to help?

Sometimes pairs circle each other tightly, with dorsal fins raised again. Any one else seen this behaviour?

Cheers

hi, i've seen two of my males doing that, but never one male with a female.
