I would only do it if you have firm plans for a larger tank. They are a big fish, and they should outgrow these smaller tanks. If they don't, you have two issues. Either the fish isn't really healthy, or you don't see that it is too large for the system. Both are common problems. You tend not to want to trade in a fish that you have grown attached to, even if it is in the best interest of the fish. So in general I discourage this unless, as mentioned, you are simply "growing it out" for a known larger system.
How old is your system?
