I have noticed a few of my fish have taken notice to my ACAN colonies all of a sudden and the acans do not look so happy. Any ideas how I can protect them from being devoured. I was thinking about an eggcrate box to keep fish away but allows them to get food, light and flow. Any other ideas as the eggcrate does not really look to good but it may have to do for now. Tank is a 120 mixed reef
