Do Mollies eat other fish?
 
I added three mollies to my tank and I had a rosy red minnow in there too (my friend's fish died and he was healthy food for the fish so I rescued him) and he has been acting nervous like a week ago (before I added the mollies) and after I added the mollies I came home one day and he was all bloody. His tail was torn (looked like fin rot) and he had two little red spots on him (it almost looked like he was stabbed/bit by something) and I moved him into a separate bowl (I've been changing the water constantly) with some aquarium salt. And he is acting normal, but he is still all bloody. Did the other fish try to eat him? And should I move him back into the tank? There is ZERO ammonia in either tank/bowl!

Or is it just a bacterial infection? If so how do I treat it?

Wow, I've never seen my molly in my fifteen gallon tank attack any of our other fish. Maybe your rosy red minnow was so small?

a rule i go by is: if it fits in there mouth there going to eat it....that way you know what size fish to mix with others and which "small" ones to keep away from :):):)
