Bigger is always better, but isn't the issue what is minimum, not what they will use. A platy will use a whole 300 gallon tank but that doesn't mean that is what is needed.

I agree 6 foot tanks are the min for any ray.. Keeping any ray in any tank under 6 feet is a waste and is very temporary as in my experience rays grow very fast until about 10 inch disc. Get a 108, or 135 for a grow out tank. Better yet get a 180, you won't be upgrading for a very long time!
