I have 2 blue guaramis that I believe have showed signs of wanting to mate. I have a 20 gallon tank set up with just the two of them in it. I was wondering, for breeding guaramis, can I put other fish in the tank as well such as a sailfin Molly and green neon tetras. They'd look great in there. Can I have other fish in there while in trying to Breed guaramis. Thanks
