Here is some more info for you to take in.
When it comes to reef lighting many think VHOs provide the best light for fluorescence. VHOs are the closest bulbs to the black light range and have the least amount of visible light as opposed to other types of bulbs offered. The problem is when you go to this range it takes more energy to gain intensity and these bulbs can appear to be dimmer than others that radiate more visible light.
An HO T5 ATI Blue Plus bulb (peek = 450nm) probably has the highest intensity of all the fluorescent bulbs offered in this range but they contain higher amounts of visible light which somewhat diminishes the "fluorescent effect" we see in VHOs. Its the lack of visible light in VHOs that gives us a wider contrast between light and subject matter.
Now lets get back to the subject matter in this case it is corals. In nature most fluorescent pigmented corals that are excited by light in the high UV range radiate fluorescent color in the green spectrum. Corals with colors such as red, orange, & yellow generally are not as fluorescent in nature with some exceptions. To bring out these colors more ~ a certain amount of visible light is desired.
For this reason a blending of bulbs is the best way to get a wider variety of corals to "appear" to fluoresce. VHOs with thier lower amounts of visible light do a great job in exciting the greener colors found in corals and don't do as good a job with reds, oranges, & yellows. This has to do more with the type of pigmenting of the corals than with the bulb itself.
In nature the corals with the most fluorescent pigmentation in the red, orange and yellow range are going to your zoanthids and your LPS corals.
