i have been wanting a catfish but cant find one to save my life that i like besides a blue cat and gulpers. i want a big fish but not one that i am going to have to up grade to a 1000g tank just yet. would like to have a rtc but i dont have the room to house one so i am going to stay away from them. i have a oscar that i am going to have to put into a bigger tank he is only about 2inches right now. but in time i will have to get him something else to stay in. what size of tank am i going to have to up grade to for my oscar plus to have enough room that i can put another big fish in. and what are my options on fish that big but not to big. i am wanting maybe a 180 or 200g what are my options?
