i noticed some interesting goings on in my tank last night, and wondered if it might be mating behavior?
i have 15 drape fin barbs--oreichthys cosuatis or oreichthys umangii--depending on which source you believe. they are beautiful little fish, silvery white with a yellow and black spot in their dorsals fins. the males develop a long, flowing gold and black speckled dorsal fin. it's really beautiful when they flare them.
here's an article:

anyway, i noticed last night that they were swimming around in m/f pairs, and rubbing cheeks. the males were flaring their dorsal fins a lot. i would automatically assume this was mating behavior, except that i saw 2 females doing it too.
not really into breeding, so i don't have much experience...
anyone know?
