I was wondering if a small Oscar could be kept in a 10-Gallon tank? If this is possible how long would the Oscar be able to stay in the 10-Gallon Tank? It would be the only fish in the tank. Thanks a bunch!
Stradius is right. One Oscar needs at least a 55 gallon tank. It may appear that a 10 gallon is enough while the Oscar is still small, but don't be deceived by that. It's best to have an Oscar in at least a 55 gallon tank from the beginning because it needs this space to grow and develop properly. In a small tank he will not get proper growth and development.
yip, you often see baby Oscars in 10 gallon tanks in the pet store bearing in mind not many fish stay there for very long. Mine are in a 300g tank and even that doesn't seem like enough space for them cos they get up to such mischief! they enjoy lots of space - nothing smaller than a 55 gallon for one and 125g for two - they messy fish and need a lot of maintenance. So if you're getting a big tank keeping you baby in 10 gallon will be fine while your new tank cycles but anylonger than that could be fatal for your little fishy. :-[
