I have a 7" Silver Aro and 2-7" Bala Sharks. They have been together for about 2 months now along with a Geo and a cpl Silver Dollars.
In the evening I have noticed that the Aro is hunting the Balas. He comes down from the top of the tank and slowly sneaks up behind one of the Bala's. If he gets close enough, he will open wide and try to clamp onto the back (behind the dorsal) of the fish. The Bala's are so fast that they get away...but there has been contact and you can see some marks on the Bala. (small but they are there).
Question is....do I get rid of the Bala's now? As the Aro grows will he end up killing the Bala's? Aro doesn't pay any attention to any other fish like the SD's which would be way easier to catch.
Why the Bala's
Soo many questions
