Well speaking purely asthetically, I love my t-5's in my growroom. I have one metalhide bulb that's 150 watts hanging over an orange tree and I've love how long it's lasted. But it's hot and anyone that wants to say they are equally hot watt for watt needs their head examined. I could put my hand on my t-5's all day long but I nearly catch my hair on fire when I accidentally get to close to my metalhalide fixture. Also, we need a big ballast that also gets hot with the metalhalide and the fixtures with t-5's plug in normally without the cord or fixture heating up.
I'm not sure how different the metal halides might be for fish than for plants. But I don't like the big ugly fixture that the metal halide comes with and the t-5's are streemlined, small, easy to mount anywhere and run cool enough to place on or near any surface.
