i seen video's of them doing it, but having a fish do it was a first for me after 6 ears. most of my fish are in pairs, granted i know most will never breed in my tank { fairy\flasher wrasse's } but was very neat to see as well as my nassarith snails started spawning at the same time and my potters started doing the dance a little, my have too catch the dragonettes and set-up a separate tank for them, not that i have time to try and raise fry nor space to do it lol but my 6 yr old daughter doesnt like the thought of the stuff being eaten lol she use to get mad if i didnt catch all the seahorse fry and seen my yw pair snatch babies out of the water
