One thing to think about if you decide to get the shrimp and goby is that pistol shrimp love to dig and can make a mess. That being said they are pretty cool to watch. By the way that light is awesome, I love everything DIY.
I would not even chance putting a anemone in the same nano tank as a white cap! It's a small chance it would get eaten but it is a 250 $ plus fish so I wouldn't chance it. I would get a really colorful yuma ! The sexies will host that too! Just my 2 cents! :bigsmile:
