My ph is 7.5, moderate hardness, temperature 79-80. Otherwise, similar to above. With an adult or near adult male and some juvies it should basically be a matter of waiting until two pair up. IME they like to have a fairly flat or smooth stone (sometimes they pick one that's upright, sometimes they pick one laying in the substrate) to lay eggs on, usually near and end of the tank or a spot with some structure they can protect. After some hours to a day or so they'll pick up eggs/wrigglers to hold in their mouths.
Both males and females will hold fry. Sometimes they'll trade off, one eats while the other holds, etc. IME you'll sometimes get some bickering between a pair, sometimes more so with a newer or younger pair. Not something to worry about ime, usually they work it out.
