Hi Everyone,
Another question.
I have 2 silver aros, One is around 3 & half months old and another one is 3 months aprox (based on the birthdays told by my LFS)
The elder one is around 6" now and it started showing a green and red shade on the body and the color is totally different from what it was earlier. (See Pic)

is this common among the Silver Aros and i am just panicking? or is it really something serious?
However i am noticing a sudden change in its behavior to the younger one. it has become aggressive. when lights are turned on it does not allow him to swim on the top and chase him towards the bottom of the tank. but when i provide food or lights are turned off, he does not have any problem him swimming on top.
Water conditions are perfect 7 PH, with No Nitrate & Nitrite.
