my oscars are around 3 inches long... i had four of them and now im down to three.. i gave the smallest away to a friend because i felt bad, the others wouldnt let him feed.. but anyway my third and biggest fish in my tank is getting beat up, im talking bad, he has got missing scales and his fins are shreded a little bit,and he tends to only use his one fin... the other two especially the albino one are just ruthless... but im not sure what i should do just wait it out? hes feeding alright,and breathing fine, just stays in the corner most the time.... i dont have onother filter for my other tank or i would put him in there.... he is my favorite of the three, and it would just suck to get rid of it... any ideas? comments? help, please..
