Hi,

I have a pictus catfish, will it be ok with a oscar and I thought the man at the pet store said it will eat live fish when it get bigger and will it become aggresive.

Pictus are great as long as you an adult one. However, it is best to have more than one, they could get stressed out on their own, and you might not see them much. Make sure it's got somewhere to hide. They will be very small fish given the chance, but were only talking things like guppies, I don't think they'd eats anything too much bigger
