i have a pair that bred a lil over a month after i got them in. currently i have the fry growing out in the tank with the parents. ive read that you can keep multiple pairs together. and yes the price is pretty steep on these if you can find them wild caught. i got mine from greg at littleafricaaquatics.com he has them listed as "dwarf" though its the same fish. you can buy F1 way cheaper from sicichlids.com and reservestockcichlids.com. tell em i sent you.
