Comments:
Rarely available in the hobby, R. lapidifer is only infrequently imported. It requires oxygen rich water. A sandy substrate should be provided and clean water is a requirement. R. lapidifer can be differentiated from other members of its genus by an absence of stripes on the caudal fin. They may bury themselves up to their eyes in sand if suddenly startled. In the aquarium, spawning starts only after a oval pit is excavated. This is usually to the glass of the aquarium. Up to 200 eggs are laid and have a bit if an adhesive nature. Although they are not attached to a stone or to the glass of the aquarium. Quite often the pair will create a new nest with rocks and pebbles. The eggs will be transferred there and a layer of sand will be spat on top of the eggs. After 96 hours the eggs will hatch. R. lapidifer are highly protective parents.

 Key To Species Profile Terms
 Pronunciation: Refer to our Pronunciation Key for an explanation of the phonetic symbols.
 Habitat: This is the primary location where the cichlid is found and is a generalization. This does not
  mean a fish cannot be found in other habitats.
 Diet: Many cichlids specialize in eating one type of food; notwithstanding, some of these specialized
  feeders are flexible and can be opportunistic feeders.
 Temperament: This describes the overall demeanor of a cichlid toward other tankmates that
  are of a different species. Consider that there is variability in temperament due to various factors,
  including aquarium size, tankmates of similar appearance, stocking levels, and order of introduction.
  There may even be some variability among individual specimens.
 Conspecific Temperament: This describes the overall demeanor of a cichlid toward other tank-
  mates of the same species. Consider that there is variability in temperament due to such factors as
  aquarium size, stocking levels and order of introduction. There may even be some variability among
  individual specimens.
 Maximum Size: This is in regards to total length (including the tail) of typical aquarium specimens.
  Wild specimens may not attain this size, or may in fact grow larger than aquarium raised individuals
  due to various factors. Also consider that this is the typical maximum size and there are exceptional
  individuals that will exceed it.
 Difficulty: This measure is a relative value, comparing a single species against all other cichlids.
  This only accounts for maintanence in the aquarium and not breeding considerations.
  1 = easy and forgiving, 5 = extremely challenging.
