I had 'breidohri' and 'Coatzacoalcos' pairs spawn at the same time. After 3 months, the 'Coatzacoalcos' are 1.25-1.5" and the 'breidohri' are barely 1". So the 'breidohri' fry are noticeably slower growing. IME other Paraneetroplus species that are slow growing are 'regani' , 'argentea' as well as many of the Astatheros. And Madagascan Paretroplus are really slow!! Here's a pic of a 20 month old male 'breidohri' (at ~ 6")
