HI so recently I've moved my female guppies to a smaller tank because the males were too aggressive. Unfortunately they've unloaded. About 15-20 fry in the last week and many of them still look squared off. I'm wondering if it would be safe to quickly cycle a ten gallon to move the fry or if it would be a bad idea to move the fry at such a small size. They are about half a cm long and about 5 days old. I just don't want my tank to get overstocked and then crash.
