So I've tried all the chemicals to kill this pest , high powered laser, file fish all he did was pick on my soft corals and did not touch the aptasia, luckily i was able to remove him before he did any serious damage now im up to Berghia Nudibranchs hope this works problem is i have a yellow coris wrasse and a Harlaquin tusk, and a black leopard wrasse and a 6 line, if this doesn't work i might try a CCB runing out of options the tank is doing great expect for this Pest anyone have any suggestions ?
