I think 250w would be fine and you could grow anything. If you could retrofit a T5 bulb front and back for actinics, it would look great. That was my original plan until I decided to go all T5 on my tank. If you go with the halides, you wil likely have heat issues as well.

He is right. I too have a 65 gallon with two 150w Metal halides with X 14k DE bulbs and two 39w actinic t5s. Lighting is a nice color and everything is growing well.
