well since it will be only pups in the tank at any given time with the angels, Im thinking of giving it a try. The angles are about 2 yrs old and are big enough to get away I hope from any pup that may get lucky catching one.
If I have any trouble, Ill just move the angels into some breeder tanks I have running.
Ive had my rays take out one of my bala sharks also. My Motoro took the head off of the bala. They were in the tank together for a long time and one day, the bala was dead. I didnt even think the ray could catch the bala, but I have a theory on how he did it.
Anyway, thanks for the info. Will be working on the change in a few days and then will see how it goes.
