I was at a LFS today and they had a two oscars, one an albino tiger and the other a tiger, they are both about 6 inches long. I have a 90 gallon tank and was strongly considering buying them and was wondering if it was ok to buy them or if I should buy juveniles instead. I would like to buy them because they would fill up a lot of the space in the tank right away rather than having to wait 6 months for a pair of juveniles to grow. They looked like they were in good shape, but I will go back another day to take a closer look and find out some other info like what size tank they were kept in etc. Thanks for any help
