I have an rbta in a 72 gallon bow front w good water parameters under kessil 150 w leds. I feed krill and silversides once a week and it became quite large. I've had him for six months in one spot on my reef and recently he split. He was stationary after the split or about a month, but now has moved to a darker area in top left corner of tank. Any ideas why he decided to become mobile? Nothing in the tank has changed over the past couple months w water quality, flow, or lighting. Thanks for looking and happy new years!
