I am selling my pair of Oscars, one is and Albino Tiger Oscar and the other is a Red Oscar they both are around or over 7 inch mark so they will need a large enough tank, atleast 55 gallon and up and have some prior experience or knowledge with these kinds of fish. They can be put in with other fish big enough they cannot eat and be able to defend themseleves in the case of aggression. If interested please email me with any questions or you can reach me on my cell and leave a message as I will return the call in a short time. I will be more then happy to answer any questions and hopefully youll be the one to take these beautiful fish home.
