Healthy Big vs Skinny Orange Sea Star Comparison

I believe they are Echinaster luzonicus

The smaller one was brought in from the office and was probably starving for several months. After trying to keep a reef in an unmodified Eclipse 6 for a year, I have to say that it doesn't work. Nothing is really fluorishing in there. The stock 8W light can not support any soft corals or polyps, not even Xenia or Green Star Polyps. The powerfilter does not provide much oxygen either.

Anyhow, the 2 stars were about the same size at first. But clearly, the one in my tank has outgrown the one from the office. You can see the tube feet on the big one but not on the small one.
