So i just rescued an oscar that i found on craigslist. he has pretty bad hith, but ive put salt in the tank and upped the temp to around 82, so that should be helping him out, but he just hangs around the bottom of the tank in one of the corners. im not sure if he is just bored in there or what. if him being bored is the case, is there anything i can put in there to entertain him i guess?
