I think it will be fine. Just keep an eye on the blenny, but it'll probably leave SPS alone. I've had a blenny start nipping at SPS and it's pretty easy to tell when they are nipping at them.
Rob,
I like the plating ones myself.....just something cool about them and most grow quickly. you can also frag numerous types together and watch them tangle as they grow. plus, in about a year, it creates a nice shaded ledge if you place it right.
My birdsnest seems to really love the LED's that for sure........but i will say that only the SPS seem to be doing really good, the LPS seem to be veeeeery slow to grow.
Are you looking to just get one? maybe start with a cheap one to see how it does under your lights, juice the power up and see how it reacts?
