Hmm... which is it, 2x 96W or 2x 65W? Yesterday you said 2x 65W.
Regardless, it doesn't look abnormal to me. In a low flow area, the tentacles won't get very long. But expansion-wise... it looks fine to me.
It all gets down to intensity. The T5HO may use fewer Watts, but they are more intense... I think the measurement of it is in "PAR". And the increased intensity also penetrates deeper into the tank. So for a given Wattage, the T5HO setup give more PAR at deeper levels, providing more photosynthetic energy to the corals. Same goes with Metal Halide... even more intense than T5HO.
