Hi Midas
There are only few basics that you need
Good water quality ph around 8.0 kh about 150ppm > 300ppm
10% water changes not too much at once
Feed high protien foods to juveniles for growth (breed American cichlids to provide wrigglers with egg sack the best food you can give them)
Use pellets as staple food with additions of live and frozen foods
Give them more than one choice of a spawning site (rock cave, large barnacle shells, bailor or helmet shell etc)
They will harem spawn so can be kept in a group aswell as a pair
Have micro worm culture as fry starter then go to new hatched brine shrimp and increase the food size as they grow otherwise jaw deformities can occur
I currently have a pair (7cm M 5cm F) of the Gold form breeding in a 24"L x 14"W x 12"H tank running at 7.8ph & 200ppm gh with sand substrate a couple of hollow rock caves filtered by a simple ice cream container filter (filled with 3mm gravel and crushed coral)
Feed them mini pellets with feedings of mozzie wrigglers, frozen brine and mysis shrimps
