Nah that silver isn't big enough to stress them... Did you try bacterial meds? And if they seem like they are acting up after a water change it might be something in your water. City water gets a lot of stuff put into it.Does anybody think this little 9" arowana could be stressing the large clowns? The one looks the worst is the large 8" and he is regularly swimming up and down in one corner yet the aro doesn't mess with them one bit and they have way more than enough hiding places. I'm also not sure but I think he seems to do it mostly after water changes.
