Hey Jerry, if you'd have waited about a week longer before you got your borellii from me, I could have called them breeding pairs. I got several pairs from a breeder, and one by one they they spawned in the holding tank. Some of the pairs have even raised some broods in there. I've set up some borellii in a separate breeding tank before. I've never had a problem with leaving earlier batches of fry in the tank. My only concern with timing in removing them is space restrictions, or fry becoming mature and interfering with the pair. I've had multiple generations of borellii in a 30, same with some cacatuoides. My problem has never been them eating their young or becoming too aggressive, but rather that they just won't stop making more babies! ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
