go to
www.google.com and type in breeding egglayers and browse through some of the entries. It is very likely your fish are trying to breed, although the chances of getting any babies to survive in a community tank are small, unless you have an abundance of plants, where the eggs and /or fry remain hidden. Everyone in the tank would be happy to eat them, including their parents.
If you want to try to get babies, set up a separate small tank with water, temp etc. the same as the original tank. Put a big bunch of plants in there, and your female. Feed her well, especially with some live or frozen food (brine shrimp, bloodworms). When she is nice and fat, add one or two males, give them a few hours, and return all parents to the main tank. You may get lucky and have some eggs, they may hatch, and you can raise them up in there. Use a sponge filter in there, operated by an airpump, not a hang-on filter.
