I've had these guys for a long time and have believed them to be a pair, but I'm not super sure because there has never been any mating/territorial behavior (however, they live with two small platy girls and the male will bite them if they get in his way).

I'd actually want to spawn them at some point (without the platies present lol), so I'd just like to know why I haven't seen any spawning behavior thus far. Could it be that they do spawn when I'm not looking and the platies eat all the eggs? Every single egg over the course of the year that I've had them?

I've got about 30 platinum wagtail fry that are 65 days old now. Just spotted this little weird one. Any idea why he's got a white patch? He acts normal but has a little wobble, probably due to a slight curve in the spine under the white patch. Anyone know what kind of mutation this is?
