My husband bought me a 75 gallon tank when we got married because aquariums are a huge passion of mine. He has made only one request though, He wants a couple/few big fish that will be impressive to look at for our home visitors. What we think that we have decided on is buying 2 juvenile Oscars and raising them up. There would be only a Raphael Catfish (4") in there with them, he is left over from my current tank. Would this work? I have been researching alot and it is pretty much a 50 50 decision on the outcome. If not what would be a good idea? We want some eventually big fish but also don't just want one fish in that HUGE (to me) tank.
