I bought an oscar two weeks ago he was pretty injured he is blimd from one eye and he was missing alot of scales and fins all torn up well his fins are now perfect and he swims around hes still blind from one eye tho but he would eat in the hospital tank but only once the food hit the bottom of the tank now hes in the main tank food doesnt get the chance to git the bottom so will he start to eat from the top? I tried sinking pellets no luck also hes 3 inches lomg how old do you think he is? And how long before he reaches 5-6 inches
