Once my sand looks clear I may try that and move my powerheads higher and lower power to coax the clowns out more. I think they are just creatures of habit at this point. The Coral Beauty has no issues with swimming all over the place. I'm still at a loss for why these other fished died. I guess it 'could' be velvet but it would be odd these others have had zero issue for so long and the dead fish all looked perfect and the only similar symptoms were breathing a bit fast and not eating for the last few days before death.So they are positioned approx 3/4 up wards, the right 10w 3/4 towards back and left 5w 3/4 towards front,
I hope this helps
