How long they pregnant for? Any usualy signs of very close to dropping? Unlike my guppies I would Like a fair few of them to survive.
about 28 days.
easy way is just wait until she drops. if you have a male in there it will be prego again. if not they can store sperm for 2-3 births so you still have some time.
should put each prego in their own tank with some moss or other plants. this will give you the best results.
