My silver aro is very skittish, not too crazy but it is annoying. All my other fish (in other tanks) swim up to the top to feed and the lame aro is terrified of everything. I put a new plant in yesterday on the far side of the tank so he is less likely to hit the glass and now he is just terrified of that side of the tank. I had to trim plants on the other side of the tank so he had to go over and deal with it. Well he insisted on freaking out and splashing all over like an idiot. He still eats well and is fine but his skittish attitude is really starting to annoy me. Someone comes over and I tell them to approach the tank slow and he still freaks and darts to one side. Does this go away or are they like this forever?
