They are actually super easy to care for. They like their water fairly calm, but they can handle some flow. If you want to pair them with other fish, avoid slow movers and those with flowing fins. Also be careful with killies when it comes to things like wafers and pellets. They can sometimes swallow those things whole with their wide mouths which can cause problems. I don't have any shipping supplies. I need to round up all that stuff so I can start shipping some stuff out. Try to make sure she has some spots where she can hide from him. They should reproduce for you (though they will eat most of the babies if not seperated, heavy planting helps though) and if you want to keep it a species tank, you could shoot for an end goal of 2 males and 5 females, and maybe your lfs will buy the extras from you, or trade for supplies. Sometime in the next month I would pick up some fry food to keep on hand.
