so the oscar in my 55 gallon has been in there for about 4 months, and he is 4.5 inches long. he used to be this very active fish, always begging for food but now after i had a firemout in that tank he became kinda/very shy after the FM showed aggression and kinda have him a sore on the top of his back (shown in the pic). i took out the FM a week ago and hes still shy. he eats food if its in his face but i dropped in a nightcrawler and he didnt even CARE!!! those are his fav! so i suspected a parasite and i treated with prazipro 24 hrs ago. when do you think he will be the personality-full fish he is? im wondering because they do pout or sulk around like after water changes but not for weeks on end. it looks like hes pouting, but endlessly. seriously any responses are super helpful
