Hello Kyle You can do all of those you asked except for sister - sister, lol, that won't work!!!! I have crossed a really nice son back to his mom a couple of times because She had some color in the fins and i was looking for more color in my Cacatuoides. Have done the same with double red color form of Aggies. Haven't ended up with tank full of mutants yet!!! But then again every so many generations I cross in new blood to my strains. Have fun and good luck. John ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
