I have a smallish RBTA in my Biocube 29. It had an anemone crab that was bonded with it, so I took that too. I put it in a spot with good flow and lighting and immediately moved. It moved under a rock, so I let it be for awhile. It finally came out, but over the last few weeks it's turned white. The crab has not left it since I got it either. It looks healthy. It's open and seems to be eating. The lighting is a retrofit LED
kit. There is 28 Luxeon 3w LEDS. I have them set to around 50%. Any ideas?
