It does look like the clowns are contemplating the gigantea as their new home. As others have pointed out, the gigantea is bleached. The fact that you've had it 6 months bleached points to it being otherwise a hardy specimen. So with the upgrade in lights, you will probably have a beautiful, healthy animal there. Good brands for T-5s are UVL, ATI, among others (go to The GrimReefers thread in the lighting and equipment forum for really good info., and if you have questions, he's quick to respond). I would suggest, if you like the blue color, to go with ATI Aquablue plus as it provides very high PAR and still gives you a blue look. Reefgeek is the best source of different brands of bulbs I've found. Do you have individual reflectors on your fixture? From my understanding, that makes all the difference in terms of light intensity at greater depths. If you don't have individual reflectors, you probably need to locate the anemone within 15 inches or less of the bulbs. Also, not sure what your water flow is, but giganteas are known to appreciate a high water flow.
