I'm becoming increasingly worried about our Aro. He doesn't seem to have as much interest in eating as he once did and he looks a little beaten up. I suspect our Oscar is picking on him. I've never seen it happen but I wouldn't put it past him. We have another tank that he would be comfortable in until he gets a bit bigger but that worries me as well--would moving him be too stressful? Should I just wait it out and see what happens? I've been throwing around the idea of using some sort of barrier to separate the two so they can both stay in the same tank until the Aro gets a bit bigger and can defend himself a little better. Thoughts?
