yes regani are dwarf( ikeep only dwarf cichlids apistos. and such) but males can get as large as 6" in captivity compared to only 4 or 5" in the wild .
the fry are quite large for dwarf fry. more than twice the size of the apisto. fry i'm used to so they are quite capable of eating baby brine shrimp . they'll soon be capable of taking small grindal worms i'm sure.
