Re: dancing albino cories...

They are going pretty crazy... and I'd prefer not to have a whole bunch of little cories. They are in with my betta, they get along great with him, but i fear that will change if spawning tries to occur... any advice would be very welcome.
Corys are in no way aggressive, even when spawning, unless you are a nice tasty worm. Corys will not eat eggs nor young. The betta may develop a taste for the eggs, but if there is any cover in the tank, like plants or driftwood, he wouldn't be able to catch the fry.
I suspect there is a low pressure system moving through your area, as corys tend to race around exactly as you describe when the weather changes like that. It doesn't mean they are spawning (though in groups they often do), especially if they are the same sex. You'd have to develop an eye to tell male and female corys apart. Females are more heavily bodied and somewhat larger than the males. You need to see a whole group of adults to learn which is which.
