Firstly the obligatory mention of Apistogrammas. Now with that out of the way I've a question for the person, apologies lost the post, who mentioned breeding D. filamentosus recently. I have 6 juveniles ranging from a bit over 1/2 an inch to about an inch, maybe less. At what size do the males develop their elongated dorsal and caudal fins? They all have a very pronounced checkered pattern at the moment.
