My female has layer eggs 3 different times in last year. I have 2 azuls in a 340 gal together. Is it possible for her to lay eggs without a male present first question. In case I'm wrong on other being a male. An 2 what can I do to help get the eggs fertilized. Cause they don't seem to be doing something right I've yet to have anything fertilzed that I've seen yet. An 3 how do I vent to make sure it's a male. Cause I kno the other is a female. Cause she keeps popping out eggs. Thanks
