Calm down?
You asked for advice, but are not providing the info so I asked again. What part of that requires anyone calming down?
Anyways, no you need a new light fixture to keep an anemone.
You want at least a 4 x 39 watt T5 HO fixture, ideally a 6 bulb would do the trick. $0 inches is an odd number, so I would get a 36 inch 6 bulb Tek light fixture. And hang it using the hanging brackets.
