Once you get your gourami out of the 60, you should be ok if you have enough plants and such for the fry to hide in. There is almost no such thing as a fish that will not eat fry except maybe cories. I have never seen a cory eat a baby fish but I know they will eat frozen, once live, food so I'm not even sure about them.
The point is simple, with enough cover, your live bearers will multiply their numbers but won't breed totally out of control. I'm sure you already know that the swords, mollies and guppies are all live bearers. Depending on which algae eaters you have, they may or may not be safe. I know plecostomus are not but I think otocinclus might be safe. I have never seen them eat anything but algae, algae wafers or flake fish food.
