Hi,
Since you have a male and 2 females you should heve no problems breeding, just provide plenty of caves and things and the male will pick out his spot. I have a big lump of mopani wood with a hole in it, leaning against the front of the tank, when they lay eggs i can shine a torch in the hole and see them, the male sits and fans them until they hatch he doesn't eat during this time, then he keeps them in the hole until the egg sack is used up them lets them out, they usually wait a couple of weeks for the babies to move out then they have a new batch. Unfortunately due to the size of the wood, i can't move it to another tank so once the babies leave the hole they are usually eaten by the loaches.
I have a few babies in another tank now which i have fished out when i have seen them near the top, they tend to sit in the floating plants. My parent fish are 3.5-4 inch female and 4-4.5 inch male, i got them in april this year and they have had 5 batches so far, i saved 2 babies from the first batch and they are 2 inches long now.
You could keep other fish in the tank with them but i would pick something like hatchet fish which will stay out of the way. If you have loads of plants and hiding places in the tank you should be able to raise them. I have at least 6 babies loose in the tank from a couple of batches ago, and a few which came out last week. My plecs are both the natural brown colour but they seem to have 25% albino babies in each batch, i have only managed to save 3 so far as they are usually the first to be eaten.
