would 2" silver dollars be too small for a 6" baracuda? i know theres always a chance they will be food but was thinking they might be to tall to be eaten.
As long as you have a good supply of feeders in there with them you will be fine. But if you miss a feeding for a day or 2, don't be suprized to find a bite mark. When young mine would eat 4-5 guppies a day. I do not think they could actually eat it, but if starved they will try.
I highly doubt it could hurt the sd's. It may try them if it gets hungry enough, they are exclusive predators after all. And they will never let go of there evolutionary traits. By the way lets see this monster. if you do not want to post pics hear. put them in my cuda thread in the media section.
