New Tank Some Help Please

  • We are currently upgrading MFK. thanks! -neo
Hey I have a question I'm new too, I have a new 100g tank with 3 young fish (about 3-4"). I have a oscar, a green terror, a Raphael Cat, and a red aureau (is that the same as a fire mouth?) anyways the Aureau is beating the crap out of the green terror. I had the oscar about 1 week and added the Aureau and GT a couple of days ago. The Oscar has started standing up for himself a of today and is running off the Aureau (the terror comes to him for protection) Can you suggest anything I can do? The Green Terrors fins are starting to look beat up. I would love to keep both fish. Did I put the wrong fish together?
