The payara now stays in a corner of the tank, hanging out behind a driftwood. The atf showed some agression initially, but now he seems ok with the payara. Bought some feeders, but the payara hasn't eaten yet. Gonna observe for a few more days, if he doesn't eat, then i'm gonna seperate the payara. Maybe he has problems hunting cause of his eyes or maybe he hasn't adjusted yet. Really like the payara, love the fangs even more. Pity haven't seen him feed yet. Waiting patiently for my lfs to bring in the one u have, like to keep a few different species of the payara. They only have the scomberoides.
