An Oscar sticky does sound nice, Tom. It is a common question, especially over the last few months. But to the OP, I wouldn't suggest a 55 hex or standard or a 60 for an Oscar for life. A 75 should be bare minimum. i think you find so many people keeping Oscars in 55s because at many chain stores this is the size that customers are told will hold an Oscar for life. I don't keep Oscars at this present time but I have friends that do. I can confidently say that a healthy adult Oscar will not live a proper life in a 12" tank. They grow large in both length and girth. If you have ever seen a healthy adult Oscar you will realize that 55s and other similar sized tanks are not good for Oscars or any other large cichlids. Don't make your judgements based on people's experience of keeping an Oscar in small tanks. It's not really truthful. Look through the threads for pictures of Oscars that are kept in proper setups. Then you will realize that tiny tanks just don't make much sense. Between all of your threads about this I'm sure that you have enough feedback to make the right decision.
