you asked which was sufficient for a growout... right?? ok, a 125 will work, but for how long? a 5-6" motoro in 6months tops will more than likely need a bigger tank... sooo why not take ur hard earned money and put it towards a bigger tank, or building your pond..? that way you dont have a 125gal just sitting there when you do HAVE to move the ray .... thats why i say none are sufficient... don't bash me for simply answering your question....
