ok i am thinking about getting a 125 for my Oscars to go in, but i wont some thing else in there with them, they have a catfish that i will probably get rid of, Silver-tip shark is going to friend who has a brackish water aquarium, and a sailfin pleco. I was thinking arowanna or jardini but are they to big for a 125g? If they are what is a good-sized schooling fish i could put in with th O's, Except tinfoil barbs i have ahd them before and although they are pretty i would like something different. and what type of catfish, should i go Pictus, Eclipse or Sunset, i am open for suggestions? Also would parrots or severum be okay. Just let me know i guys i had an idea about if but first i want to see what you guys have to say about it. Thanks all and pics will be coming soon, hopefully
